445	[bug] Darwin string buffering segfault in examples/shootout/revcomp.pir	allison	mikehh	"examples/shootout/revcomp.pir (which is also t/examples/shootout_17.pir) is failing with a segfault on MacOS 10.5.6. I would assume that this is just a broken XCode install on this machine, but it appears that jkeenan was failing the same test in TT #438. So, I'm skipping this test on darwin for now. You can duplicate the failure with:

{{{
./parrot examples/shootout/revcomp.pir < examples/shootout/revcomp.pir_input
}}}

gcc installed with XCode 3.0 gives the following error:

On some research, the missing cpu_capabilities.h appears to be a problem with an (incompletely or badly) upgraded XCode install. Upgrading to XCode 3.1.2 changes the error in gdb to a more obscure and less useful:

{{{
