This was detected with ASAN, but can also be seen without ASAN with: $ tac - - <&- tac: standard input: read error: Bad file descriptor *** Error in `tac': malloc(): memory corruption: 0x... * src/tac.c (copy_to_temp): Don't close our output stream on (possibly transient) output error, or on input error. (temp_stream): clearerr() on the stream about to be reused, to ensure future stream use is not impacted by transient errors. * tests/misc/tac-2-nonseekable.sh: Add a test case. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/25041
