>Synopsis: malformed markup triggering mandoc segfault
>Category: user
>Environment:
System : OpenBSD 7.1
Details : OpenBSD 7.1-current (GENERIC.MP) #575: Mon Jun 6
10:11:31 MDT 2022
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
With certain malformed markup, mandoc segfaults attempting to access
fields
on a null roff_node pointer at tag.c:102 in tag_put
>How-To-Repeat:
Run mandoc on the attached manual page with malformed markup
(unterminated "Oo" followed later by "Tg"). This may not be a minimal
reproducer but
hopefully it's reasonably close for debugging.
