Some of the tests for Boost.LexicalCast fail on any MSVC compiler. Unfortunately currently I have no access to Windows.

I can run as many tests with vc10, vc11 and vc12 for you as you like.

This is one of the failing cases:

----------------------------------------------- #include #include

meerkat::CatchUnhandledExceptions CrashHandler;

int main() { char A = boost::lexical_cast<char>("A"); } -----------------------------------------------

which causes

That's a good place for me to start! Thanks for finding that out! -- Best regards, Antony Polukhin
