Which versions did you try? :)

bash-2.05b$ gcc-3.0 -fPIC -g test-fpic.c; ./a.out

gcc version 3.0.4

Crashes under 3.0.4, looks like the possible PIC register bug we saw
with the double printf. I recommend you move to a newer gcc if possible.
I spent a few minutes looking at assembler output and %r19 looks to low
to be valid...
