When mkstemp fails, the template buffer may have undefined contents, so we must not print it. * src/sort.c (create_temp_file): Use temp_dir, not "file" when diagnosing failed mkstemp, because "file" may be undefined. * tests/misc/sort-merge: Adjust for new expected output. Jeph Cowan and Ralf Wildenhues reported the test failure: http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/14235/focus=14257 * src/tac.c (copy_to_temp): Don't use template buffer after failed mkstemp call, since its contents may be undefined. * tests/misc/tac (pipe-bad-tmpdir): New test for the above. * src/mktemp.c (main): Save a copy of the template string, solely for use in case mkstemp fails. * tests/misc/mktemp (pipe-bad-tmpdir): New test for the above.
