Summary

0004937: Bad interaction between camlp4o and optional arguments

Description

The following program is incorrectly preprocessed by camlp4 :

~ 12:59:36 $ cat rien.mli
type option = int
val f : ?l:bool -> unit
~ 12:56:56 $ ocamlc -pp camlp4o -c rien.mli
File "rien.mli", line 2, characters 8-23:
Error: The type constructor option expects 0 argument(s),
but is here applied to 1 argument(s)

Sorry I couldn't guess the source of the problem !

Notes
(0005192) pveber (reporter) 2009-12-10 13:26	Yes the problem appears to be similar to issue 4884 (apologies for missing that one), but I should stress that in my case camlp4 is necessary for the problem to appear : ocamlc -c rien.mli works just fine. Anyway thanks for this lightning-fast reaction ! ph.
