Enabling MALLOC_DEBUG results in unreliable Asterisk behavior including a couple segmentation fault scenarios.

Attaching several traces and logs.

Two traces and log sets from when it crashes and dumps on startup. One trace from when it actually started up successfully and then dumped after "core stop now". I didn't get a log to go with the shutdown dump.

Other than crashing on startup and sometimes running, then dumping on shutdown, Asterisk also occasionally freezes during startup with

> I am trying to investigate a possible memory leak issue with release 13.5.0. In order to have better information I enabled MALLOC_DEBUG on menuselect compiler flags.
