On the trunk r129918 configured:
../trunk/configure --with-arch=r5000 --disable-java-awt --without-x
--enable-__cxa_atexit --disable-jvmpi --disable-libgomp --disable-static
--enable-languages=c,c++,java --disable-fixed-point --enable-checking=release
--with-gmp=/home/daney/mp --with-mpfr=/home/daney/mp
With glibc-2.6.1
I am getting (with n32 ABI):
FAIL: gcc.c-torture/execute/nestfunc-6.c execution, -O2
FAIL: gcc.c-torture/execute/nestfunc-6.c execution, -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/execute/nestfunc-6.c execution, -O3 -g
FAIL: gcc.c-torture/execute/nestfunc-6.c execution, -Os
All these cases are failing with SIGSEGV
It seems that they used to work:

------- 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
*** This bug has been marked as a duplicate of 32406 ***
