Ok, I missed updating libc :) Now fixed. I'm however getting:

task /sbin/getty(631) looked up a bogus port 4294967295 for 28000, most probably a bug.

it seems the extension of MACH_PORT_DEAD doesn't work.

Thanks for checking. I think the comparison in gnumach will always be false because the name is up-cast to a mach_port_t.
However, this change does not seem to be a no-op since we haven't seen this message before, right?
