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
