             Summary: New pattern matcher matches invalid patterns
                 Key: ASTERISK-29510
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29510
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/PBX
    Affects Versions: 18.5.0
            Reporter: N A
            Severity: Major


Thought I would give the new extenpatternmatcher a try, but it seems to be completely missing some pattern matches.

As soon as I disable the new pattern matcher, everything works again.

I don't know what the status of this new pattern matcher is today, and whether or not it is supposed to be ready for primetime, but this does seem like a pretty major bug with the PBX core. Here is debug 10:

	same => n,Answer()
exten => e,1,Goto(done,1)

It *should* be going to _[A-Z]. but is instead matching on e, which isn't even a valid match for the extension in the first place.
