Description:I'm using this ael syntax for pattern match for hint
       hint(SIP/${EXTEN}) _ZXX => NoOP;
when I tried to subscribe, it causes asterisk to crash.

subscribe to "normal" match hints using this ...
       hint(SIP/761) 761 => NoOP;
... works fine.

pattern match for hints feature was added into trunk in rev. 109970





****** ADDITIONAL INFORMATION ******

 '_ZXX' =>         hint: SIP/${EXTEN}                            [pbx_ael]
                   1. NoOP()                                     [pbx_ael]

e->data can be NULL, so use the safe version of ast_strdup()

thanks for fix for crash when subscribe to pattern match for a hint.
another issues still exists:

- crash when do 'ael reload', if I have pattern match for hints in extensions.ael:
hint(SIP/${EXTEN}) _ZXX => NoOP;
gdb2.txt uploaded

- when use pattern match for hints, all subcribed lines have status 'idle', even in case, that peers are not registered.

Also make sure hinting won't crash on reload.
