In my pcre.mli this error is not mentioned.
There is a
type error =
| Partial (** String only matched the pattern partially *)
| BadPartial (** Pattern contains items that cannot be used together
with partial matching. *)
| BadPattern of string * int (** [BadPattern (msg, pos)] regular
expression is malformed. The reason
is in [msg], the position of the
error in the pattern in [pos]. *)
| BadUTF8 (** UTF8 string being matched is invalid *)
| BadUTF8Offset (** Gets raised when a UTF8 string being matched with
offset is invalid. *)
| MatchLimit (** Maximum allowed number of match attempts with
backtracking or recursion is reached during matching.
ALL FUNCTIONS CALLING THE MATCHING ENGINE MAY RAISE
IT!!! *)
| RecursionLimit
| InternalError of string
(** [InternalError msg] C-library exhibits unknown/undefined
behaviour. The reason is in [msg]. *)
Which also mentioned a partial-match error.
But Pcre.Error(0) looks somehow cryptical
and strange to me.
Maybe that old version is just too old.

Yes, I think that makes sense.
But Pcre.Error(0) is not very verbose, and I also want to know
what I catch and why...
Installing a newer pcre was easy, but then my build process complains
about multiple stublibs-directories. So I threw it away.
So maybe it's better to change the apt-get stuff instead.
(I also tried to create a pcre-ocaml PKGBUILD for Arch Linux, but
I would need to fake the install-drectories, so that it would install
locally inside the fakeroot... any ideas on that?)
Ciao,
Oliver
