Try modifying the function in Host.mm:
static short GetPosixspawnFlags (ProcessLaunchInfo &launch_info)
by commenting out the following lines:
// Close all files exception those with file actions if this is supported.
flags |= POSIX_SPAWN_CLOEXEC_DEFAULT;
Using this flag used to cause kernel panics. Maybe it still does on 10.7? Let me know if this fixes things and if it does, then I will place a dynamic MacOSX version check for 10.8 and above.

I'm not an OSX developer normally so it's quite possible that I'm doing something wrong and I'm wondering if anyone has any pointers.
