Hello

I want to catch exceptions into strings. I do not want to have pre-defined exceptions in my module which can be handled. I want to catch exceptions like "floating point exceptions" etc. 

I wrote the follwing piece of code:

value divide2 p = 2/p ;

value foo p =
        try divide2 p
        with
        [e -> let _ =  do {print_string (Printexc.to_string e);flush stdout} in  9];

value _ = foo 0;

(This code is in the Camlp4 revised syntax).

When I compile and run this code, I get :

Floating point exception


However, after loading OCAML, if I use this file, I get

 value divide2 : int -> int = <fun>
value arbit : int -> int = <fun>
Division_by_zero

That is, in the latter case, I get what I want but in the former case, I don't. Could you help me solve this problem ?

Gaurav
