libgomp.c/ordered-1.c and libgomp.c/ordered-3.c currently timeouts on my system
(RedHat 8.0 with 2.4.18-14, i686) due to unimplemented FUTEX syscall.
strace of produced binary shows endless lines of "Function not implemented"
lines. This is the beginning:
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
write(4, "[EMAIL PROTECTED]@[EMAIL PROTECTED]@\340\370\377\277\0\0\0"..., 148) =
148
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
rt_sigsuspend([] <unfinished ...>
--- SIGRTMIN (Real-time signal 0) ---
<... rt_sigsuspend resumed> ) = -1 EINTR (Interrupted system call)
sigreturn() = ? (mask now [RTMIN])
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
futex(0x40019458, FUTEX_WAIT, 0, NULL) = -1 ENOSYS (Function not implemented)
...
Breaking execution in the middle produces following backtrace:
Program received signal SIGINT, Interrupt.
