Building Pari-2.1.5 (from http://www.gn-50uma.de/ftp/pari/00index.html) fails
when trying to compile src/basemath/buch2.c with -O3 on a SuSE 8.2 system, the
compiler aborts with a "internal compiler error" message.

gcc --version
gcc (GCC) 3.3 20030226 (prerelease) (SuSE Linux)

Unfortunately I have no stock gcc 3.3 available to test.

Compiling with -O2 seems to work:

/usr/bin/gcc -c -O2 -Wall -Wno-implicit -fomit-frame-pointer -o buch2.o -x
cpp-output  buch2.i

I'll attach the "buch2.i" file to this report.
