Using a lightly modified config (RT#57532), I got parrot to build as a 64-bit Intel binary on OS X. One of a series of segfaults encountered appears to be triggered in Parrot_memalign in config/gen/platform/darwin/memalign.c (if gdb is to be believed) while running test 19 (and possibly also 17, 19 was the first I reproduced) of the shootout tests. I do not currently have an extensive stack trace of this crash; the crash reporter and gdb encountered difficulties due to the addresses involved. This is quite possibly the first time I've seen a crash that the crash reporter couldn't generate a trace for.
