Subject: Crash when run against groff tbl(1) output
Date: Tue, 14 Oct 2014 00:07:19 -0600 [thread overview]
Message-ID: <15458.1413266839@cathet.us> (raw)
I ran "tbl /usr/share/man/man6/phantasia.6 | mandoc". I don't know what I
expected, but I didn't expect this:
Program received signal SIGSEGV, Segmentation fault.
0x00001c3b46c3d9f6 in term_tbl (tp=0x1c3e10d58a00, sp=0x1c3de3073f40)
at tbl_term.c:104
104 if ((TBL_OPT_BOX | TBL_OPT_DBOX) & sp->opts->opts ||
Here is a reduced (possibly nonsensical) form of that input that triggers
what I hope is the same crash; backtrace follows.
.TS
.if !'\n(.z'' \!.foo
.de bar
..
\!.baz
.baz x
