While creating a larger VCL-application (with BCB5) I got a priviledged instruction at runtime. I could get rid of it, when recompilig the complete project, instead of actualizing, but later this didn't help anymore. Just when I thought I got rid of it yesterday (after excluding some tests) it reappears after some very(!) small changes in a TMenuItem in the source-code and long before it comes to the changed place. The situation at BCB5 is that it now occurs before reaching WinMain() at all. So how to debug, if one can't set a breakpoint, not even to WinMain. Displaying the stack-window the following appears: Jconss::initialization __Exception Handler __Exception Handler c:cppbuilderbincc3250mt.dll c:windowssystem32kernel32.dll When porting the project to BDS2006 the problem is mainly the same. In BDS2006 it passes WinMain, but such a priviledged instruction occurs when doing a trivial things like AnsiString txt=...; char *str=txt.c_str(); // here the priviledged instruction appears So it seems that something has gone wrong before and the assignment is where the problem shows up. I suppose this is the worst case scenario: an error which occurs sometimes or sometimes not (after changing some source-code anywhere) and the position where it appears is another one that the position where the real error occurs. Is there a way how to find the real cause of this problem? Thanks a lot, Michael Back to top Larry Griffiths Guest Posted: Thu Feb 02, 2006 2:39 pm    Post subject: Re: Priviledged instruction at runtime at 'strange' location We were having Priviledged instruction problems but it came down to the .tds files being greater than around 27meg I think. One of our folks on the Enterprise version of BCB5 can only set debugging on for two projects in the project group at a time. You could turn off all debugging and do a build all and see if the problem goes away. I however have the pro version of the BCB5 and don't seem to have this problem. <MR> wrote Quote: While creating a larger VCL-application (with BCB5) I got a priviledged instruction at runtime.

You could turn off all debugging and do a build all and see if the problem goes away. I however have the pro version of the BCB5 and don't seem to have this problem. Thanks a lot for the answer... When I first tried this compiling without debug-info in BDS2006 all went fine. Trying to recompile it with the debug-info again kept this exception away too. But not for long. It seems a little bit wicked to be forced to recompile all without debug-info and than again with to be able to debug, but to make a not-so-short story short, it seems the problem is in the precompiled header. If I remember correctly, Borland told that a problem with a defect precompiled header occurs in BDS2006, Patch1 and suggests to delete it manually. The only problem is the compiler did not find any problem: the problem occurs when the program is running. ~~~~~~~ Trying not to use the precompiled header file in BCB5 leads in my project also to an adress exception (even if it was no priviledget error) and this is the one before WinMain... Trying to compile it with all three debug-checkboxes excluded in the project-options-Compiler-Debugging does not change the problem: the stack at this point is only slightly different: __setenvp __Exception Handler __Exception Handler c:cppbuilderbincc3250mt.dll c:windowssystem32kernel32.dll ~~~~~~~ So if someone has an idea about how to move on (in BCB5) it would be highly appreciated (, but so far I am happy the problem does not occur any more in BDS2006, when not using precompiled headers).
