This problem seems to be specific to ppc. I was unable
to reproduce it on ia32.

I cannot reproduce this as of today for sure, does is this fixed for you too (maybe something is being
miscompiled as I only built with -O0).

Can't reproduce it with the 20040919 build.
And galgel also compiles with -O2 and runs to the end,
so it's time to celebrate. If you close the PR, maybe you can
add this testcase to the suite to prevent future regressions.
