Just a quick report:

	mona:~ 4> cc -o simpletest simpletest.c 
	simpletest.c: In function `RetAddrOkay':
	simpletest.c:87: warning: unsupported arg to `__builtin_return_address'
	simpletest.c:88: warning: unsupported arg to `__builtin_return_address'
	simpletest.c:89: warning: unsupported arg to `__builtin_return_address'

	simpletest.c:92: warning: unsupported arg to `__builtin_return_address'
	mona:~ 5> ./simpletest 
	Segmentation fault (core dumped)

I'll look into this a bit more later if you have no bright ideas :-)
