okay, it seems that gcc with -fstack-protector (default) and -O2 places
the variables wrongly on the stack. I can give more insight if desired.
Basically listen_set is at -72(%ebp), whereas the canary is already at
-40(%ebp). sizeoF(fd_set) == 128, so figure :)

this regression should be pushed upstream. joerg, do you handle this?
