[perl #73608] [BUG] Rakudo (nqp-rx) regexes won't backtrack properly into capturing parentheses or subrules

[Patrick R. Michaud via RT]

Now fixed in 9005478:

  pmich...@plum:~/rakudo$ ./perl6
  > say "aaaab" ~~ /(.*)b/;
  aaaab
  > say "ab" ~~ / (ab|a) b /;
  ab
  > grammar G { regex TOP { <foo> a }; regex foo { a* } }; say
?G.parse("aaa");
