MSVCRT*.DLL is the VC++ C runtime.  Cygwin has it's own so you have to be
*real* careful to not mix the two in any way.  Doing so can cause crashes.

Your environment in general looks OK now.  I see that you're even trying a
snapshot of the Cygwin DLL.  Good for you! ;-)  This is somewhat bleeding
edge code though so if you suspect an issue is Cygwin-based, drop back to
1.5.21 (or 1.5.19 if you must) to make sure that it's not something new.
