Description Ville Skyttä 2004-12-05 18:04:59 EST

Running the following command (don't ask ;) makes troff reproducibly segfault:

  zcat -f /usr/share/man/man4/ptmx.4.gz | nroff --legacy ISO-8859-1

This is groff-1.18.1.1-3 on FC3.  Backtrace attached.

Comment 2 Miroslav Lichvar 2006-01-10 08:09:20 EST

Manpage ptmx.4 includes man4/pts.4 therefore the command has to be run in
/usr/share/man directory. Otherwise groff will not find the file and abort.

Comment 3 Ville Skyttä 2006-01-10 10:40:10 EST

Aborting or erroring out is ok, crashing is not.  But anyway, it no longer
crashes in FC-4 and Rawhide so I don't care that much (nor can I any more test
with FC-3).

Comment 4 Ville Skyttä 2006-01-10 14:05:44 EST

Oops, it seems to crash in FC-4 (1.18.1.1-5) and Rawhide (1.18.1.1-7) still
after all -> reopening.

A graceful exit with an error message would be much more acceptable than a
silent core dump.

Comment 5 Miroslav Lichvar 2006-01-12 09:58:58 EST

Ok, there was a problem with assertion failure. Fixed in rawhide.
