>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>    Affects Versions: 11.22.0, 14.1.1
>         Environment: Note: not tested with 14. Instead, tested with a fairly recent master (bf01ff53f8d93d637981720331405e56f0b3b118), on both my Debian Testing laptoop and a Centos 6 server.
>            Reporter: Tzafrir Cohen
>            Severity: Minor

> When app_macro considers the dialplan extension to execute, it loops through contexts and fails to protect from an infinite loop. The result may be a crash with over 5700 recursive calls to find_matching_priority() called from macro_exec().
> Reproduce: An Asterisk system with the following dialplan:
> {code}
> [test]
> include => test2
> include => test1
> exten => macro,1,Answer()
>  same => n,Macro(test)
>  same => n,Hangup()
> [test2]
> include => test
> [test1]
> exten => s,1,NoOp(Starting Macro)
> [macro-test]
> include => test
> {code}
> Now call the macro. E.g.:
> {code}
> channel originate Local/macro at test Application Wait 40
> {code}
