Hello,

>> My program written in ocaml terminate with the following output:
>> Fatal error: exception Invalid_argument("index out of bounds")
>> So how should I find out the lcoation in source code that raise this exception?

> you can run your program in bytecode setting the OCAMLRUNPARAM correctly and you'll see the whole backtrace, like in
> OCAMLRUNPARAM=b ./myprogram

Just remember to compile with the -g option to really get the backtrace otherwise you'll get something like
   Fatal error: exception XXX
   (Program not linked with -g, cannot print stack backtrace).

Regards,
