Description Dmitry V. Levin 2004-07-17 15:44:26 UTC 
When traced process receives signal which will be handled, strace may
decide that process is going to die and will detach from this process.

It happens because sigishandled() sometimes incorrectly returns 0 due
to hex string parser bug in parse_sigset_t().
