Does crtdbg.h conflict with DirectX?

Question

I just discovered the hidden gem crtdbg.h which makes memory leak detection so much easier. Unfortunately, when I linked DirectX into my program today, I got some errors I've never seen before.

1>e:\program files (x86)\microsoft directx sdk (june 2010)\include\d3dx10math.h(425): error C2059: syntax error : 'constant'
1>e:\program files (x86)\microsoft directx sdk (june 2010)\include\d3dx10math.h(425): error C2091: function returns function
1>e:\program files (x86)\microsoft directx sdk (june 2010)\include\d3dx10math.h(425): error C2802: static member 'operator new' has no formal parameters

It seems like when crtdbg overrides the new operator, it breaks something in the DirectX SDK (in case you didn't notice in the errors, I am using the DirectX 11 SDK). Is anything like this documented? A few searches didn't yield any results. I really hope I can continue to use these memory debugging tools, and any workarounds would be greatly appreciated!

No repro. Use the C/C++, Preprocessor, Generate Preprocessed File option. Open the generated .i file, find _D3DXMATRIXA16 back and post what you see. And document version numbers. — Hans Passant, Jun 10 '12 at 14:55
@HansPassant I don't see that option, the closest thing I can see is "Preprocess to a File", but it tells me it can't find "base.obj", which is my base.h/base.cpp file. I solved it, however. — smoth190, Jun 10 '12 at 19:17
@HansPassant Its ok, I fixed it. I don't know where the linker error came from, other than the fact that it only happened when I used that setting. — smoth190, Jun 10 '12 at 19:58

Ok, I figured it out. I found this post via Google. (I wish Stack Overflow had shown it to me on the sidebar when I was typing this! Or maybe it did and I missed it...).

Basically, I need to move the including of crtdbg.h, stdlib.h and the definition of _CRTDBG_MAP_ALLOC to a separate header, and use the Forced Include File option under C/C++ >> Advanced in the project properties page to force that include file everywhere. This seems to make it override all other new overrides.
