> If the Directory application is called with the 'a' (alias) option then the Asterisk process stops with a segfault the moment the caller presses a DTMF key. The Directory application works normally if the 'a' option is not used. Reproduced with latest snapshot from certified/13.1 as well.
> [Edit by Rusty - adding Chet's new description on how to reproduce]
> Hello. I think I found the exact way to reproduce this. I tested with Asterisk GIT-13-87c03b7. In summary, when using the "a" option it doesn't like any mailboxes defined with a name and nothing else.
> I stripped down the test to barebones dialplan:
> Dialplan
> {noformat}
> exten => ##94,1,Directory(,internal,fa)
> {noformat}
> Working voicemail.conf
> {noformat}
> [general]
> [zonemessages]
> [default]
> 4405 => 2580,Fred Jones,,,alias=leader
> 4406 => 2580,Velma Dinkley,,,alias=genius
> {noformat}
> If any mailbox is defined like:
> {noformat}
> <mailbox> => <password>,<name>
> {noformat}
> with nothing else then it will segfault.
> If the mailboxes with a name at least end with a comma then aliases will work. For example:
> {noformat}
> <mailbox> => <password>,<name>,,,alias=My Alias ; With an alias defined.
> <mailbox> => <password>,<name>, ; A comma added.
> <mailbox> => <password>,<name>,,,alias= ; Alias parameter but no alias defined.
> {noformat}
> then the Directory application works as expected.
> Backtrace will be attached. Last 10k lines of debug will be attached.
> For reference the segfault was at:
> {noformat}
