Package: ocaml-nox
Version: 3.11.2-1
Severity: normal

ocamlbuild enters an infinite loop if a symlink creates a cycle in the source directory.

To produce the problem:

1. cd to the source directory of a project using ocamlbuild
2. do "ln -s . loop"
3. run ocamlbuild

Ironically, I discovered this while trying to prevent *my* OCaml code
from exhibiting this same problem.  When I created a cycle to test it, I
couldn't build the program any more :-)

It doesn't run forever for me (with ocaml 4.01.0). It takes a long time
(11 minutes), but it terminates successfully.

Anyway, I agree with Mehdi and I won't work on this bug nor forward it
upstream. Feel free to do it if you really want ocamlbuild to support
symlink loops. Hence, I'm closing this bug.
