[Bug c/39277] New: Segmentation fault when compiling arith1.c of Pari/GP 2.3.3/2.3.4 with -O3

["Michael dot Finken at me dot com" <gcc-bugzilla@gcc.gnu.org>]

I am compiling version 2.3.3 (or 2.3.4) of the Pari/GP math library. The
compiler crashes with a segmentation fault, when the source file arith1.c is
compiled with -O3.

The compiler is gcc 4.3.3, freshly compiled on Solaris 2.8.

Here's the log output of the compile:
