[Openal] Problem between debug and release build

[timo at futuremark.com]

It is common, and the reason is virtually always in your own code. Maybe 
you have a buffer overflow somewhere.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_core_common_problems_switching_from_debug_to_release_build.asp

Try to add this in the beginning of your code:

# include <crtdbg.h>
# define new DEBUG_NEW

    _CrtSetDbgFlag(
		_CrtSetDbgFlag(_CRTDBG_REPORT_FLAG) 
		| _CRTDBG_CHECK_ALWAYS_DF
		| _CRTDBG_DELAY_FREE_MEM_DF
		| _CRTDBG_LEAK_CHECK_DF
	);
    /*_CrtSetBreakAlloc(0); */

You may want to comment out the check always line. Run your code with the 
above lines in debug mode and see if you get any assert failures. If you 
do, comment out stuff from your code so that you no longer get those 
failures. And if you get memory leak errors when you exit your program, 
get the last (lowest) memory block id, and place it inside break alloc 
call and enable the call. That way you get a break when the problematic 
block is being allocated the next time your run your program.

Good luck hunting memory trashing bugs, they are nasty sometimes.
