> Maybe I'm just hallucinating, but if I goto(mysw-17-3,label)  and have these extensions defined:
> _mysw-17-.
> _mysw-1-.
> mysw-17-
> mysw-17-*
> mysw-17-2
> mysw-17-1
> s
> The last match I would expect would be the second item in the list above, but that's the one that is chosen.
> ****** STEPS TO REPRODUCE ******
> Define (in AEL or extensions.conf) :
>  context test394 {
>     s => goto mysw-15-OK|label;
>     mysw-15-OK => {
>     label:
>           Set(zz=3);
>       goto sw-17-${zz}|label2;
>     }
>     _mysw-1-. => { label2:NoOp(in exten _mysw-1-.); goto s|1;}
>     _mysw-17-. => { label2:NoOp(in exten _mysw-17-.); goto s|1;}
>     mysw-17- => { label2:NoOp(in exten mysw-1-); goto s|1;}
>     mysw-17-* => { label2:NoOp(in exten mysw-1-*); goto s|1;}
>     mysw-17-2 => { label2:NoOp(in exten mysw-1-2); goto s|1;}
>     mysw-17-1 => { label2:NoOp(in exten mysw-1-1); goto s|1;}
> }                                                                                                                                                   
> load it into asterisk, and on the console:
> *CLI> dialplan show mysw-17-3 at test394
> [ Context 'test394' created by 'pbx_ael' ]
>   '_mysw-1-.' =>    1. NoOp(in exten _mysw-1-.)                   [pbx_ael]
>                     2. Goto(s,1)                                  [pbx_ael]
>   '_mysw-17-.' =>   1. NoOp(in exten _mysw-17-.)                  [pbx_ael]
>                     2. Goto(s,1)                                  [pbx_ael]
> -= 2 extensions (4 priorities) in 1 context. =-
> I really can't warp my brain to understand why _mysw-1-. is even in the list,
> because the - just before the dot in the mysw-1-. pattern should have disqualified that pattern!
> But, if I'm missing something (and I'm known to do that!), please let me know!
> ****** ADDITIONAL INFORMATION ******
> BTW-
> This little tidbit of information has nothing to do with this bug, but the new pattern matcher selects the expected exten, mysw-17-.
