I already had a critical section protecting against multiple-thread reentrancy in AllocationHook When I stated the problem this way, I realized that all I needed was a variable in thread local storage that I would access at the beginning of AllocationHook If the value was greater than 0, AllocationHook was being reentered as part of the MessageBox processing and I just needed to bail out of the function I implemented a quick dynamic thread local storage solution and my anxiety dropped considerably because everything started working as planned I thought I had everything rolling at this point, but I noticed my second stress problem When testing the code to fail on a specific source and line, the source filename was coming in as NULL and the source line was 0.

Because I was using MFC for the MemStressDemo program, I thought it would have done the right thing and properly used the CRTDBGH versions of the allocation functions to pass in the source and line Alas, that wasn't the case I figured that all I needed to do was to drop in a define of _CRTDBG_MAP_ALLOC at the top of STDAFXH and include CRTDBGH as the end of the file Of course, as soon as I compiled, the spew of redefine and unexpected constant errors overwhelmed me No matter what I tried, I could not make an MFC application compile and use the proper version of the allocation functions After a while I found that the only thing I could reasonably do was extract the defines from CRTDBGH and include them manually in STDAFXH You can look at the MemStressDemo's STDAFX.
