          Components: Resources/res_phoneprov
    Affects Versions: 1.8.16.0

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:
