the divm function destroys my input variable

[GoogleCodeExporter]

What steps will reproduce the problem?
1. python gmpybug.py

What is the expected output? What do you see instead?
I expect the program to terminate normally, all assertions should succeed, and 
the final print statement should be executed.
The numbers printed after the ++++ and after the ---- should be equal, since 
they are the same number.

What actually happens is this:
++++

Thanks for the report. I have corrected the bug and released a new version. 
gmpy2 2.0.4 is now the recommended version.
