------- Comment #1 from daney at gcc dot gnu dot org  2007-11-11 06:29 -------
The problem is that $gp is clobbered at the nonlocal_goto_receiver but it is
not being restored.

Currently the nonlocal_goto_receiver has a condition of
TARGET_CALL_CLOBBERED_GP, but this is not correct.  I think it should be
unconditional.

In:

http://gcc.gnu.org/viewcvs?view=rev&revision=125941

I renamed this from exception_receiver. I wonder if the exception_receiver
really should be conditional on TARGET_CALL_CLOBBERED_GP in which case there
should be both an exception_receiver and nonlocal_goto_receiver.  It would seem
so as the unwinder should restore $gp making it redundant in the
exception_receiver.

Hmm.  This is really the same as bug 32406  I will mark it as a duplicate and
reopen 32406
