[Boost-users] boost::variant build crashes Visual C++

25 Mar 2008

      Hello,

I have a simple program to test boost::variant.  Under Visual C++
2005, configuration Release (/MD), the build fails with C1060 (out of
heap space).  The program compiles and runs as expected under Visual
C++ 2005 Debug (/MTd), and under Visual C++ 2008 Express, Release and
Debug.

Below is the code.  Any idea what's wrong?

Many Thanks,
Eric
