Even though the Debug build appears to be symptom free you might want to try
the _CrtSetDbgFlag(_CRTDBG_CHECK_ALWAYS_DF); approach. If your code is
single threaded it should find any heap corruption within your code.

If this is truly a Release build only issue then you might want to check the
myriad of debug iterator preprocessor defines to ensure they are consistent
between your project and the Boost.DateTime version you are using.
Have you ensured that _SECURE_SCL=1 in your project for the Release

If your project is fairly small and you are allowed, I would be happy for
you to send the Visual Studio solution to my personal email address so that
I can take a quick look at it. This might be the fastest way to proceed.

Did you mean Multi-Threaded DLL (/MD) and Multi-Threaded Debug DLL (/MDd)?
IIRC the Boost shared libraries build against the shared C runtime by
default and these should not be mixed.

I hope this helps,
