My personal build of CMark ✏️
man: use a variable to store the char * from node_get_url.
We get segfaults on some platforms when we do
cmark_strbuf_printf(man, " (%s)", cmark_node_get_url(node));
but they go away with:
url = cmark_node_get_url(node); cmark_strbuf_printf(man, " (%s)", url);
I don't understand why.
Closes #253.
