Hi,
This is the same bug as the one reported in
https://lists.gnu.org/r/bug-bison/2020-03/msg00009.html: Segmentation fault
with symbol_code_props_get at src/symtab.c:457. So it is also fixed but the
fix I sent.
commit 641e326303753575664ca146fee7e9148d6bf5cf (HEAD -> maint)
Author: Akim Demaille <[email protected]>
Date: Fri Mar 6 09:05:52 2020 +0100
code: be robust to reference with invalid tags
Because we want to support $<a->b>$, we must accept -> in type tags,
and reject $<->$, as it is unfinished.
Reported by Ahcheong Lee.
* src/scan-code.l (yylex): Make sure "tag" does not end with -, since
-> does not close the tag.
* tests/input.at (Stray $ or @): Check this.
Cheers!
