Debugging Information Corrupt

[Tim Roberts]

If I build an application in debug mode in Visual Studio 2005 that happens
to reference something in the oleacc.idl, and I link it with the brand-new
Windows 7 SDK, I get a linker error complaining about the debug information
in the library, suggesting that I recompile it. The error only happens
with the /debug switch to the linker.

If I were actually invoking <oleacc.h> by hand, as in my test app, I could
include <initguid.h> before it to eliminate the external reference.
However, in my case, <oleacc.h> is being brought in by ATL, and it might
not be convenient to use <initguid.h> on every GUID. The problem does not
occur with the Vista SDK.

I don't seen any references to this problem on the web, but I can't imagine
I'm the first one to encounter this. This is a minimal test case, but I am
seeing this with production apps.

C:\tmp>type x.cpp
#include <windows.h>
#include <oleacc.h>

int
main()
{
return (int)&IID_IAccessible;
}

I saw a hotfix for this problem somewhere. It might be this one:

Excellent -- that fixes it. A rare failure in my Google-fu.

I think it was discussed also in the Windows SDK Blog:
