if it's aborting, that is wrong .. send me the .s file please.
it should do (something like) this (with or without stack check):
$ ./sc
[address=bf7ff848 pc=00001ced insn=00040c83] Segmentation Fault
on ppc the message should also identify that the stack has overflowed.
The program is meant to allow one to check that the correct code has been
generated - by scanning the RTL and/or asm. The result of execution should be
a caught segfault.
