You really can't rely on line numbers when you are referring to things like this.
I don't have a sigproc_printf in my version of sigproc.cc at line 675.

Probably the right way to fix this is for the parent process not to
deliver the SIGCHLD to itself until the child has actually been suspended.
I don't know of any way of figuring out if the child is really suspended
though.

Upping the thread priority in sig_handle_tty_stop would make the race
less likely, too.
