Perl segfaults with a regex_sets error message #14851
The search on this bug tracker doesn't seem to search issue descriptions, but in any event I can't figure out how to tell if this is a duplicate or not. Searches for the test case, regex_sets, segfault, and the first bad revision id didn't reveal any obvious duplicates.
Test case is the 12-byte file:
dcollins@nagios:/usr/local/perl-afl/out/allcrash$ ../../bin/perl -w f2i000041
Git bisect revealed:
Change /(?[...]) to have normal operator precedence
