Your approach seemed fine -- strace it, look for important differences.
You were quite right to pick up on the difference in sigsuspend()
behaviour, but in reality it's going to be a false positive, so you
should keep looking for other differences.

And as Andrew says, give us enough information to reproduce for
ourselves -- and describe the real problem, because 'rt_sigsuspend()
does not return -EINTR' isn't it, although was a reasonable enough
assumption on your part.
