Same behavior with openSUSE 11.1 (glibc 2.9, gcc 4.3.2, gmp 4.2.3, mpfr
2.3.2).
Note that I build with -D_FORTIFY_SOURCE=2 -fstack-protector.
I get the failure Richard mentioned when I use -D_FORTIFY_SOURCE=2
-fstack-protector but no failures without those options. This is on
powerpc64-linux (but defaulting to -m32) with:
RHEL 5.3
GCC 4.3.2
GMP 4.2.4
MPFR 2.4.1
MPC 0.6
I don't normally use those options.

Ah, that helps. I was able to reproduce the failure using
just -D_FORTIFY_SOURCE=2. However when I used both -D_FORTIFY_SOURCE=2
*and* -fstack-protector the error went away again.
I'm using gcc-4.1.2 if that matters, perhaps there's a bug
in -fstack-protector in that version that masks this.
Anyway, thanks both of you for helping to track it down. I'll forward this
along to the MPC maintainers.
