It just remembers "most recent mark" in the backtracking frame. Philip -- Philip Hazel -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev

This was an obscure bug, which got the backtracking wrong. It was even wrong for /(?>a(*:1))b(?>)(*SKIP:1)x|.*/ and I am amazed nobody spotted it earlier. The bug was in the interpreter; JIT did not have the bug. I have fixed it and committed the patch. Thanks for the report. The pattern now matches "abc", as does Perl.
