We have hit the error while running 089. FSTYP -- ext3 PLATFORM -- Linux/x86_64 localhost 2.6.32-109.el6.x86_64 ... ... completed 50 iterations completed 50 iterations completed 50 iterations -completed 50 iterations completed 10000 iterations directory entries: t_mtab Ran: 089 Failures: 089 Failed 1 of 1 tests This is not very easily reproducible, however one can hit it eventually when running 089 in the loop. The problem is apparently, that the output might get lost, probably due to some stdio buffer weirdness. This commit workaround the issue by adding an optional argument to the t_mtab to specify output file. The t_mtab output is then appended to a file which content is then printed to the stdout as it would if no output file is used. With this commit applied the problem is no longer reproducible.
