Hello,


I'm teseting my code in the toplevel, and see no problems.
I use the ocamlc-compiler and it produces this message:


  "The type of this expression, ('_a, `_b) Hashtbl.t,
   contains type variables that cannot be generalized"

The line, where the problem occured was an unused
Hashtable-Creation.

When I removed that line, or when I added a Hashtbl.add,
the message disappeared.

Why is this a problem?

The line was:
  let entry_hash = Hashtbl.create 100000

The added line, which lets the error-message disappears
was:

   Hashtbl.add entry_hash "foo" "bar"


Any hints, ewhat the problem is?


Regards,
   Oliver
