very small testcase demonstrating bug
the third param to a routine (follows a large pass-struct-by-value) doesn't
quite make it:
$ ./test_gcc
addresses (caller): 0xbee27450 0xbee271f8 0xbee26fa0
addresses (callee): 0xbee27450 0xbee26d44 0xbee26fa0
$ ./test_clang
addresses (caller): 0xbecfc450 0xbecfc1f8 0xbecfbfa0
addresses (callee): 0xbecfc450 0xbecfbd24 (nil)
(see attached testcase)
