Sean Bright closed ASTERISK-20434.
----------------------------------

    Resolution: Workaround Available

This module has changed significantly since 1.8.16.0 was released and I am doubtful that this is reproducible in Asterisk 13 (the oldest currently supported version of Asterisk).

If you are able to reproduce this crash with Asterisk 13 or newer, please feel free to re-open.

> Asterisk Core Dumps when calling  "module reload res_phoneprov.so" if the polycom profile use the PP_EACH_EXTENSION to build multi line key registrations. It will also eventually happen when calling unload/load on res_phoneprov.so. The gdb output is as follows:
