The problem come from a buggy gcc which did not create frame pointers
(due to -fomit-frame-poitner) but the assembly tried to access it
anyway.

It is possible to work around it by adding -fno-omit-frame-pointer for
linuxthreads.old/* as the attatched patch does.

I assume the patch is not needed for newer gcc's.
