Hi,
i'm trying something like this:
let start () =
try pipe#run() with
Unix.Unix_error(_,_,_) -> print_string "matched\n"
| _ -> print_string "not matched\n"; raise e ;
start();;
where pipe is a http_client's pipeline.
The output is:
not matched
Fatal error: exception Unix.Unix_error(38, "connect", "")
what's wrong here? shouldn't the expression Unix.Unix_error(_,_,_) match
this error?
btw this error occurs only when running under oUnit.
Any clues?
Michael

I had this problem once, it was due to a library that was incorrectly
packaged. The library was built like this :
ocamlc -a -o foo.cma unix.cma foo.cmo ...
i.e. the library itself included unix.cma. When I built my program
like this :
ocamlc -o my_prog unix.cma foo.cma my_prog.ml
it had this behavior (the exceptions escaping the try .. with).

Thanks, this was indeed the cause of the problem.
