It crashes because you're trying to mix two incompatible runtimes together
-- Cygwin and MSVCRT. Short answer: don't. Long answer: use mingw32 GCC
with MSVCRT add on (or use -mno-cygwin, but you'll need to do some specs
editing and also need to download my msvcrt add on package).

You'll have to use a version of GCC that uses MSVCRT instead of Cygwin.
