Bug description

Full_Name: James Leifer
Version: 3.02
OS: Mandrake 8
Submission from: oto.inria.fr (192.93.2.2)

There seems to be a problem with Str.regexp or Str.global_replace....

Consider the following program:

(* grbug.ml )
open Str ;;
print_string ((global_replace (regexp "x?x?") "yyy" "zzz") ^ "\n") ;;
( end of grbug.ml *)

When I build and execute it, I get a stack overflow error:

$ ocamlc -o grbug str.cma grbug.ml
$ ./grbug
Fatal error: uncaught exception Stack_overflow

Fun with nullable regexps. Fixed 2001-08-30 by XL, using same strategy as in
sed and perl.
