Bug description

$ cd /tmp && echo -e '\nvalue f x = ();' > q.ml && echo ==== && cat q.ml && echo ==== && ocamlc -w A -pp camlp4r q.ml -o q.byte

value f x = ();

File "ghost-location", line 2, characters 8--1:
Warning 27: unused variable x.

The location is wrong (bad file name, bad "end offset").
This error exists in 3.12 too (reproduced with the same command line).
