This crash occurs on Windows but not on Linux. It appears to be a bug in GMP 
when 
compiled on Windows using mingw. I added a test in gmpy.c to force small vlaue 
of a 
float to zero before calling GMP.

Patch will be committed in a few minutes.

Changed state: Fixed

This turns out to be a bug in GMP 4.2.1 that is fixed in GMP 4.2.2. It is not OS
specific other than that I built the Windows binaries using GMP 4.2.1 because 
that
version of GMP is still licensed under LGPL 2+.
