Function return with errno 4 not 110. The expected output should like: sem_timedwait ret=-1 failed.errno=4 Real timeout=3948us sem_timedwait ret=-1 failed.errno=4 Real timeout=3929us sem_timedwait ret=-1 failed.errno=4 Real timeout=3958us sem_timedwait ret=-1 failed.errno=4 Real timeout=4149us sem_timedwait ret=-1 failed.errno=4 Real timeout=3967us sem_timedwait ret=-1 failed.errno=4 Real timeout=3818us sem_timedwait ret=-1 failed.errno=4 Real timeout=3978us sem_timedwait ret=-1 failed.errno=4 Real timeout=3965us sem_timedwait ret=-1 failed.errno=4 Real timeout=3994us sem_timedwait ret=-1 failed.errno=4 Real timeout=4035us sem_timedwait ret=-1 failed.errno=4 Real timeout=3910us sem_timedwait ret=-1 failed.errno=4 Real timeout=3982us sem_timedwait ret=-1 failed.errno=4 Real timeout=4045us sem_timedwait ret=-1 failed.errno=4 Real timeout=3892us Thanks! -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
