It looks to me like re-raising *does* preserve the location where the
exception was created.  My toy example:


--8<-- raise.ml ---
let f () = raise Not_found
--8<---------------

--8<-- main.ml ---
try Raise.f () with e -> raise e
--8<--------------

% ocamlc -g -o go raise.ml go.ml
% ./go
Fatal error: exception Not_found
Raised at module Raise, character 26
Called from module Main, character 14
Re-raised at module Main, character 32


I remember one of the developers mentioning this behavior in a discussion a
while back.

cheers,
William
