> Ubuntu Server 14.04.1 LTS (GNU/Linux 3.13.0-35-generic x86_64)

> 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.
> Backtrace will be attached. Last 10k lines of debug will be attached.
> For reference the segfault was at:
> {noformat}
> May 14 11:43:19 Cherry-Red kernel: [1833492.105879] show_signal_msg: 24 callbacks suppressed
> May 14 11:43:19 Cherry-Red kernel: [1833492.105885] asterisk[14204]: segfault at 0 ip 00007f815b4fb331 sp 00007f80f282d160 error 4 in libc-2.19.so[7f815b468000+1bb000]
> {noformat}
> Called application using the following dialplan:
> {noformat}
> exten => 2,1,NoOp()
> same => n,Set(current_menu=2,1)
> same => n,Set(CHANNEL(language)=system_prompts/directory)
> same => n,Wait(1)
> same => n,Directory(,${CONTEXT},fa)
> same => n,Set(CHANNEL(language)=)
> same => n,Background(user_prompts/751)
> same => n,WaitExten(5)
> {noformat}
> The Directory works as expected if we use:
> {noformat}
> same => n,Directory(,${CONTEXT},f)
> {noformat}
> Problem appears to be 100% reproducible once the 'a' option is added.
