             Summary: pattern [:space:] shortcut not matching as expected
                 Key: BIT-1497
                 URL: https://bro-tracker.atlassian.net/browse/BIT-1497
             Project: Bro Issue Tracker
          Issue Type: Problem
          Components: Bro
    Affects Versions: 2.4
         Environment: Running tests using Bro 2.4.1 (precompiled from http://download.opensuse.org/repositories/network:/bro/xUbuntu_14.10/) on Ubuntu 14.10.

Running using a simple "/opt/bro/bin/bro myscript.bro" syntax.

I'm trying to do some RegEx-like pattern matching of a data stream using Bro, and I'm finding that, at least some of the shortcuts, like '[:space:]' don't seem to act as expected.

In short, I expected that '[:space:]' and '[ \f\n\r\t\v]' would be interchangeable, but that doesn't seem to be the case.  I have not tested any other shortcuts like '[:alpha:]', '[:digit:]', etc.  Just '[:space:]' so far.

I will attach an example script, as well as a file containing the output I'm seeing.
