[Bug c/71287] Possibly broken invocation of connect (and maybe other) syscalls
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71287 --- Comment #13 from Artem Polyakov --- Oh, now I see what was going on! This is a really masked error: while( (rc = connect(sd, (struct sockaddr*), addrlen) < 0) && (errno == EAGAIN) ); instead of: while( (rc = connect(sd, (struct sockaddr*), addrlen)) < 0 && (errno == EAGAIN) ); so the problem is in the code, not GCC: wrong operation sequence: rc = (connect(sd, (struct sockaddr*), addrlen) < 0) instead of (rc = (connect(sd, (struct sockaddr*), addrlen)) < 0 So we can safely close this bug report. Sorry for the false alarm.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71287 --- Comment #5 from Artem Polyakov --- Thank you, Marek. I will check gcc 5.3. However SLURM is mostly used on RHEL systems and it seems that RHEL is very conservative about gcc: RHEL 6.5: gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4) RHEL 7.3: gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4) So I'd like to have some guidance regarding those old versions. And find out precise circumstances where this problem occurs.

Also GCC 4.8 is not supported anymore.
