Re: Dynamic Allocation Problem...

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The only legitimate failure from malloc() is a NULL pointer, and,
this happens when your process is out of memory.

In all other cases, your application must have corrupted the internal state
of the heap, and your code enters the reign of the undefined behavior.

Please compiler your application in release mode, and run it under
debugger after having enabled full page heap.
c:\debuggers>gflags -p /enable InDevelopmentApp.exe /full
c:\debuggers>start cdb -g -G InDevelopmentApp.exe
The heap instrumentation activated by gflags.exe is likely to put you
very close to the place where the corruption has happened.
