please try the following code:

Running "ocaml" on it (latest CVS-version) will throw an exception:

Fatal error: exception Invalid_argument("String.sub")

Thank you for the bug report.

It was a stupid error, one that cannot be caught by the compiler:

I wrote j - i in place of j - 1

Hard to see, if the font is not properly chosen!

It is corrected in the release branch.
