[perl #129322] S_invlist_clear(SV *): Assertion `invlist' failed(regcomp.c:8527)
Message ID:
rt-4.0.24-21812-1475766563-822.129322-15-0@perl.org
The call from regcomp.c:15315 (S_handle_regex_sets) has:
  SV* u = NULL;
  [...]
  _invlist_union(lhs, rhs, &u);
.. but that calls Perl__invlist_union_maybe_complement_2nd() with &u as 'output', which is documented as "SHOULD BE DEFINED upon input".

Karl, can you take a look?

Hugo
