The compiler itself segfaulted. I don't see how that can be caused by
MPIR. You aren't even linking with MPIR at that point. You are only
including gmp.h whilst compiling something else.

In order to build the MPIR test suite after building MPIR with
--enable-fat, gmp.h must be included and compiled. So we know the MPIR
code itself should be ok.

The bug may be triggered when building Pari against some version of
MPIR, but in this case it is far more likely the bug is elsewhere.
Certainly there is a bug in gcc irregardless, as compilers are not
supposed to segfault, no matter how broken the code is you are
compiling (unless you have some broken environment variables hanging
around).
