[Bug libc/3225] New: aligned_restore_vmx corrupts stack pointer during sighandler

fweimer at redhat dot com
Since the commit in
http://www.sourceware.org/ml/glibc-cvs/2005-q4/msg02674.html, there is a tiny
window during __longjmp() where the stack pointer register (r1) is undefined.
When a signal handler arrives there, the task crashes while setting up the
signal stack.
