Committed in revision 427380


Bugs: ASTERISK-24307
    https://issues.asterisk.org/jira/browse/ASTERISK-24307


Repository: Asterisk


Description
-------

Any time a stringfield is blanked it currently prevents any currently allocated memory from being freed.  If a stringfield is repeatedly set to blank then set to a non-blank value, it causes new pools to be continuously allocated and never freed.

I'm unsure if the loop can be optimized, maybe the break can be re-added to the original location on the condition that ptr == __ast_string_field_empty?

Testing
-------

Manual test using https://github.com/elessard1/asterisk-lab/blob/master/examples/lab_stringfields_leak.c to verify that old pools are now freed.

Full testsuite against Asterisk 13.


Thanks,

Corey Farrell
