Hello all First I would like to say... Nice work! I have tested memory manager replacements [Intel PIII 533 WinXP Home C++Builder 6 with sp4] by adding units to one of my projects, one memory manager per build, as first unit in project manager. Sources from borland.public.attachments Subject: Fastcode MM B&V 0.36 Date: Sun, 8 May 2005 22:17:35 +0200 Message-ID: <427e74bf (AT) newsgroups (DOT) borland.com> Xref: newsgroups.borland.com borland.public.attachments:8908 I am not benching results, just evaluating application performance with enhanced memory managers. TopMemory seemed to perform best in my application as is Topmemory, HPMM, Qmemory, EWCMM open run no errors Bucketmem, MultiMM, RecyclerMM, Access Violation on close FastMM, FastMM3, PSDMemoryManager runtime error 204 on run HeapMM EListError on close WinMM runtime error 227 on run Is there anything I should do or could do to fix AVs and runtime errors? Do I need to change project options? All compile and link... I would especially like to make BucketMem C6 compatible because my procedures completed fastest with it. I dont know how to stop AVs on closing my application. Does anyone have any advice or comments about this?

Does anyone have any advice or comments about this? I suggest you make a backup of your project and then remove as much of it as you can, without removing the error. Try to make an example as simple as possible that reproduces the error, preferably everytime. If you post this example this might either be very helpful to the FastCode MM project (if the bug is in the memory managers) or it might help us solve your problem (if the bug is in your code).

Hi Avatar, I tried creating a new project rather than cutting out code... Then I used the project manager to rightclick project1.exe->add... BucketMem.pas I dragged BucketMem.Pas to the top so it compiles first (just below project1.exe in projmanager) add/remove packages uncheck all but Borland Standard Components build with runtime packages=unchecked In project source... <PROJECT value="Project1.exe"/> <OBJFILES value="..PastestBucketMem_ASM.obj Project1.obj Unit1.obj"/> ... <LIBRARIES value="rtl.lib vcl.lib"/> <SPARELIBS value="rtl.lib vcl.lib"/> <PACKAGES value="vcl.bpi rtl.bpi vclx.bpi"/> I click run... and see a blank form When I close it by clicking x...I see dialog --------------------------- Debugger Exception Notification --------------------------- Project Project1.exe raised exception class EAccessViolation with message 'Access violation at address 0045539A. Read of address 00C05C9C'. Process stopped. Use Step or Run to continue. --------------------------- OK Help --------------------------- I view cpu window from Exception Notification Dialog It is stopped on line that reads 004550E4 jz +0x17 004550E6 mov ebx,[eax+0x0c] <-stops here 004550E9 test eax,eax 004550EB jz +0x0a mov ebx,[eax+0x0c] is also where it stops in my app. Sorry for the clutter but I am trying to be cl Is there anything else I should try?

Hi Pierre I am not certain I am doing this correctly, but I am using project manager to drag unit to top just below project.exe this results in these line in project source... <PROJECT value="Project1.exe"/> <OBJFILES value="..PastestBucketMem_ASM.obj Project1.obj Unit1.obj"/> should I try using #include BucketMem.hpp in a specific location?

Hi, Quote: I am not certain I am doing this correctly, but I am using project manager The easiest way to find out if it is the first unit that is being initialized is to trace into your program (F7 in Delphi, probably the same in BCB) and check that the initialization section of the replacement MM is the very first initialization section of all the units you use. The symptoms you describe is typical of another unit being initialized before the replacement MM and allocating memory using the Borland MM. Some MMs check whether there is already memory allocated when it starts up (PSDMM, FastMM, FastMM3) and throws a runtime error right there. Others don't check for it, but cause a crash when the memory that was allocated by the Borland MM is attempted to be freed by the replacement MM... this error typically occurs at program shutdown.

I removed BucketMem.pas I added #include "BucketMem.hpp" before all else in unit1 header no more AVs Thank you!

I'm afraid i can't help you further here, because i don't have C++Builder. If i do something similar using Delphi i don't get any errors (however if i try to link in BucketMem as an obj file i can't compile, getting an error message about 16-bit fixups and missing references). I guess someone who does use C++Builder should try this and see if they can find the cause. Back to top Bcc32 Guest Posted: Sat May 14, 2005 9:12 pm    Post subject: Re: Is MM C++Builder 6 friendly? Hi Avatar I was adding BucketMem.pas to my project, but this gives me no control over initialization timing. I was doing this for all MMs I removed BucketMem.pas and included BucketMem.hpp generated by C++Builder as the first #include in Unit1.h. No more Access Violations on Application Close!

I ones tested a custom manager and if my memory serves me right you should add add it to project source (not one of the units), since this is where your program starts, so you don't mix allocation from the Borland memory manager with the custom memory manager you want to utilize. In the menu of BCB choose project -> view source to edit this source. /Palle Back to top Bcc32 Guest Posted: Sat May 14, 2005 10:21 pm    Post subject: Re: Is MM C++Builder 6 friendly? Hi Palle mmm... I will try this now, no AVs but maybe still not quite right... I see what you mean. Im sure I don't want some hybrid memory management issues popping up when I am expecting something else... Thanks for the tip.

Hello all As a followup to my prior post... First I commented out #include <BucketMem.hpp> in Unit1.h I tried adding the line #include <BucketMem.hpp> as the first include of my Project1.cpp this resulted in Borland mm I believe (slow) so I commented that out. then I tried adding the line USEUNIT("BucketMem.pas"); so it now looks like.. //--------------------------------------------------------------------------- #include <vcl.h> #pragma hdrstop //--------------------------------------------------------------------------- USEUNIT("BucketMem.pas"); USEFORM("Unit1.cpp", Form1); USEFORM("Form3.cpp", Form3); USEFORM("Form4.cpp", Form4); USEFORM("Form2.cpp", Form2); //--------------------------------------------------------------------------- WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) { try <chop> this has worked great so far Maybe this is the proper way...
