The Machine has one of the newer P4 w/ SSE3. After some Debugging i figured out that the call to Move(SrcProc^, NewMove, SizeOf(NewMove)) from John O'Harrows FastMove.pas (the one from Dennis' Page) fails. There is no crash, no Exception .. nothing. The Program just terminates during initialization without saying anything. It took a while until i asked myself "Could it be the DES (Data Execution Prevention) of Windows XP/SP2 ?". So i disabled it by adding /noexecute=AlwaysOff to the boot.ini and it started to work. This Move does work with DEP enabled on my Athlon XP System and on my Pentium M Notebook, only the P4 System prevents it. oh and, (i forgot) while debugging i wasn't even able to check if SrcProc is NULL "if Assigned(SrcProc) then ...". This check was enough to make Windows(?) terminate the App. Anyone an idea how to workarond this ?

What happens if you use VirtualProtect to assign PAGE_EXECUTE_READWRITE permission for that block of memory? http://msdn.microsoft.com/library/en-us/memory/base/virtualprotect.asp Back to top John O'Harrow Guest Posted: Fri Mar 18, 2005 4:49 pm    Post subject: Re: FastMove with XP SP2-DES enabled This bug was fixed in version 2.10 (the version on Dennis's page is still 1.60) Version 2.3 (the latest released version) can be found in the attachments newsgroup regards, John.
