ocp-grep: Stack overflow at the end of search

[HyunggyuJang]

I’m experimenting your marvelous tool, ocp-grep since merlin doesn’t support project wide occurrences search

But, after (seemingly) successful retrieving, it dies with an error message of

ocp-grep: internal error, uncaught exception:  
          Stack overflow  

Steps to reproduce

1. Clone https://github.com/ocaml/ocaml

2. In cloned folder, type

   ocp-grep Path.constructor_typath

3. It will spit

   ocaml ❯ ocp-grep Path.constructor_typath
   typing/path.ml:112:let constructor_typath = function
   typing/path.ml:120:  match constructor_typath p with
   typing/subst.ml:124:  match Path.constructor_typath p with
   typing/path.mli:48:val constructor_typath: t -> typath
   typing/env.ml:1142:  match Path.constructor_typath path with
   ocp-grep: internal error, uncaught exception:
             Stack overflow

Environment: Mac air 2020 m1 Monterey 12.3.1.

Thanks for your help!
