Hello,
is this a known bug?
Needed to change code from
with Invalid_argument("Strings.sub")
to
with Invalid_argument("Bytes.sub")
The code now looks like this and then works again:
try
if parser_url_len > 0 && parser_url = String.sub
url 0 parser_url_len then parser_name else aux tl
with Invalid_argument("Bytes.sub") -> aux tl (*
this happens if url is shorter than parser_url *)
Ciao,
Oliver

Why do you match on the error string? String.sub is only documented to
raise "Invalid_argument _".

Even if it's not technically a regression against the specification as per
Benjamin's message above, breaking working code is still not very good.
Could you please report this on the OCaml bugtracker?

Also it's strange to get Messages that indicate error-reason in the
wrong place.
Ciao,
