Reproducible troff segfault
Last modified: 2007-11-30 17:10:56 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-22.214.171.124-3 on FC3. Backtrace attached.
Created attachment 107918 [details]
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.
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
Oops, it seems to crash in FC-4 (126.96.36.199-5) and Rawhide (188.8.131.52-7) still
after all -> reopening.
A graceful exit with an error message would be much more acceptable than a
silent core dump.
Ok, there was a problem with assertion failure. Fixed in rawhide.
