This looks like a known problem with flexdll 0.25, which affects the OCaml Cygwin package. But that is version 3.12.0 and not 3.12.1.

The Cygwin package will soon be updated to 3.12.1 without the bug.

The OCaml 3.12.1 package seems to be available in Cygwin now. Could you please upgrade in Cygwin and let us know if the problem persists?

OK, I loaded 3.12.1 from another site (mirrors do not seem all up-to-date). Now comes something different:

berry@apsara ~
# ocamldebug
Fatal error: exception Invalid_argument("inet_addr_of_string not implemented")

berry: same for me
ocaml irc says that

My cygwin install was done yesterday, so it is something else...

OK, I have the same problem with the new cygwin package. It seems the auto-configure script did the wrong thing when building the package. I'm looking into the problem.

The new cygwin package is now available (3.12.1-2). Can you try it and let me know if it works for you?
Thanks.
