Hi!
For ppc32 this just removes '\0' character that has been printed after
the register dump and before the backtrace.
For ppc64 libSegFault.so printed complete garbage.
2006-09-16 Jakub Jelinek <jakub@redhat.com>
* sysdeps/powerpc/powerpc32/register-dump.h (register_dump): Don't
write '\0' to the fd.
* sysdeps/mach/hurd/powerpc/register-dump.h (register_dump): Likewise.
* sysdeps/powerpc/powerpc64/register-dump.h (register_dump): Likewise.
Change regs to unsigned long pointer from unsigned int, fix fscr offset.
