Bug description

    Objective Caml version 3.01

Str.search_forward (Str.regexp_string "a") "a" 0;;

• : int = 0

Str.search_forward (Str.regexp_string "a*") "a" 0;;

Uncaught exception: Not_found.

Str.search_forward (Str.regexp_string "[a-z]*") "a" 0;;

Uncaught exception: Not_found.

Str.search_forward (Str.regexp_string "[a-z]+") "a" 0;;

Uncaught exception: Not_found.

Str.search_forward (Str.regexp_string "a+") "a" 0;;

Uncaught exception: Not_found.

I think that using Str.regexp rather than Str.regexp_string will what
you expected.
Str.regexp_string creates a reg. exp. matching exactly the given string.
Str.regexp creates a reg. exp. as you defined in the string in
parameter.

    Objective Caml version 3.01

Str.search_forward (Str.regexp "a") "a" 0;;

• : int = 0

Str.search_forward (Str.regexp "a*") "a" 0;;

• : int = 0

Str.search_forward (Str.regexp "[a-z]*") "a" 0;;

• : int = 0

Str.search_forward (Str.regexp "[a-z]+") "a" 0;;

• : int = 0

Str.search_forward (Str.regexp "a+") "a" 0;;

• : int = 0
