From d261dfa94ff4ab757aca23ebaeeb5112a571f0b1 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Tue, 15 Apr 2014 00:41:09 +0000 Subject: Using macros in .Sh header lines, or having .Sm off or .Bk -words open while processing .Sh, is not at all recommended, but it's not strictly a syntax violation either, and in any case, mandoc must not die in an assertion. I broke this in rev. 1.124. Crash found while trying to read the (rather broken) original 4.3BSD-Reno od(1) manual page. --- mdoc_validate.c | 18 +++++++----------- 1 file changed, 7 insertions(+), 11 deletions(-) diff --git a/mdoc_validate.c b/mdoc_validate.c index 6f78f7b2..fc0b6e18 100644 --- a/mdoc_validate.c +++ b/mdoc_validate.c @@ -1950,7 +1950,7 @@ static int post_sh_head(POST_ARGS) { struct mdoc_node *n; - const char *secname; + char *secname; enum mdoc_sec sec; /* @@ -1962,15 +1962,8 @@ post_sh_head(POST_ARGS) secname = NULL; sec = SEC_CUSTOM; - n = mdoc->last; - if (n->child) { - assert(1 == n->nchild); - n = n->child; - assert(NULL != n); - assert(MDOC_TEXT == n->type); - secname = n->string; - sec = a2sec(secname); - } + mdoc_deroff(&secname, mdoc->last); + sec = NULL == secname ?
