Bug description

Full_Name: Aleksey Nogin
Version: 3.07+13 (2004-01-04) from CVS
OS: Red Hat Linux 7.3
Submission from: charter-242-037.caltech.edu (131.215.242.37)

In the current CVS version of OCaml, if a file is preprocessed with camlp4, then
the debugging information (such as the one printed in OCAMLRUNPARAM=b
backtraces) has an empty file name. This used to work correctly in 3.06.

% cat test.ml
let _ = List.nth [] 1;;
% ocamlc -g -custom test.ml
% env OCAMLRUNPARAM=b ./a.out
Fatal error: exception Failure("nth")
Called from file "test.ml", line 1, character 21
% ocamlc -pp camlp4o -g -custom test.ml
% env OCAMLRUNPARAM=b ./a.out
Fatal error: exception Failure("nth")
Called from file "", line 1, character 21
% ocamlc -v
