>Release:        4.4-RELEASE
>Organization:
bsd4us.org
>Environment:
FreeBSD gemini.bsd4us.org 4.4-RELEASE FreeBSD 4.4-RELEASE #3: Sat Oct 20 15:53:44 EDT 2001     root@gemini.bsd4us.org:/usr/src/sys/compile/GEMINI  i386
>Description:
man(1) dumps core on some manpages (I believe these are not preformatted pages).  groff(1) also dumps core with any (or no) options.  The specific error is a segmentation fault from groff: troff.  Backtrace shows in main()->free()->free().  When attempting to recompile groff with symbols, the problem disappears.  Subsequent builds did not restore the problem.
>How-To-Repeat:
Install clean from a 4.4-RELEASE cdrom.  Run man(1) on a manpage for which a preformatted version does not exist on disk.
>Fix:
Compile and install groff from /usr/src/gnu/usr.bin/groff.  It appears that the source code on the 4.4-RELEASE cdrom does not contain the bug.
