Description Ville Skyttä 2004-12-05 23:04:59 UTC 
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 13:09:20 UTC 
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 15:40:10 UTC 
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 19:05:44 UTC 
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 14:58:58 UTC 
Ok, there was a problem with assertion failure. Fixed in rawhide.
