Unfortunately I can reproduce it with GMP 4.1.4 now :(
This is on an Athlon64 with Suse 10.0, using the GMP 4.1.4 coming with the
distribution.
What do we do?
BTW, the GMP people have a big notice on their web page that recent gcc
versions often miscompile GMP. That could of course be a problem of the GMP
code as well, but maybe the GMP testsuite should be used regularly to test GCC
builds.
This is especially important since gfortran relies on GMP and MPFR working
properly.
