--- Comment #10 from Scott Gayou <sgayou at redhat dot com> ---
This reproducer seems to require adjusting the maximum stack size.
i.e.:
$ ulimit -s 8192 && c++filt < poc -t
does NOT crash
whereas:
$ ulimit -s 2048 && c++filt < poc -t
Segmentation fault (core dumped)
This looks to be another potentially duplicated CVE.
See the following:
CVE-2018-18484: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87636
CVE-2018-18701: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87675
CVE-2018-18700: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87681
All appear to be the same root cause.
