Hi,

I noticed that several testcases in the GMP-4.3.2 test suite are failing now which
did not happen with GCC 4.9.0.  I debugged the first one, mpz/convert, and found
the file mpn/generic/get_str.c was miscompiled.

It's interesting you stumbled on this. I've seen this issue come and goas well in some of my integration testing work with the trunk.
