Did you do a 'make clean' prior to 'make install'?
By: nick (nick) 2005-01-30 10:40:37.000-0600

I can't dup either, so I'd say so...

Might be time for cleancount++ :)

Hmmm... it appears that the "variable replacement" code is tripping up here. Notice that the buffer passed to process_text_line has _only_ "group" in it, so something odd is going on here.

andrew, please post your zapata.conf so I can see what's going on. Thanks.

Patch removes the broken and unneeded variable replacement code that was part of ASTERISK-3063099.

Fixed in CVS head, thanks!
