These seem to be the bad guys. This test only fails for me with -O0,
but passes on all other compiler options.
I think the problem is that this test requires the increase in stack
size in atmega128-exp.sim file, i.e., you have to replace
set_board_info gcc,stack_size 400
with
set_board_info gcc,stack_size 2048
or it won't have enough stack to run the test.
Don't forget to also move bss to external memory with:
set_board_info ldflags "/home/pmarques/dejagnuboards/exit.c
-Wl,-u,vfprintf -lprintf_flt
-Wl,-Tbss=0x802000,--defsym=__heap_end=0x80ffff"
or some other tests might fail too.
