Regexp compile error

Anonymous — Thu, 06 Dec 2001 15:33:10 -0000

I just stumbled across a failed assertion on a Regexp
that works in Pcre:

Objective Caml version 3.02

# #load "re.cma";;
# let r = Re_perl.re "(.*?)(\WPl|\Bpl)(.*)";;
val r : Re.t = <abstr>
# let rc = Re.compile r;;
Uncaught exception: Assert_failure ("re.ml", 30636, 30648).

I guess the reason is that \W matches a character while
\B doesn't, which is no problem with an NFA that
can backtrack.

Yours, Florian Hars
