exception error trace back in ocaml

["lin hong" <lhong@amnh.org>]

Hi all,

I have problem getting a full traceback of some exception error. The
traceback looks like this:

Fatal error: exception Invalid_argument("index out of bounds")
Raised at file "camlinternalLazy.ml", line 33, characters 10-11
Called from file "list.ml", line 74, characters 24-34

But that's all I got, both camlinternalLazy.ml and list.ml are ocaml
source code, I still don't know which part of my code trigger it. Also, in
camlinternalLazy.ml line 33, there is a "try .... with e -> raise e", is
this the reason I don't have a full traceback -- Maybe something else
catch the "raise e" ?  Any idea?

Thanks.
Lin
