Please follow the instructions in doc/backtrace.txt of the Asterisk source directory to get a backtrace that you can upload here so we can see what is up.

Here it is. Compile options include DONT_OPTIMIZE and MALLOC_DEBUG.

The other file is the message left by the dying asterisk about freeing some unused memory, which I obtained before performing the backtrace that you requested.

Fix a double free issue with the Pickup dialplan application.

As part of the pickup process the connected line information is updated.
Part of this process does a shallow copy of the target channel's connected line
information to a local structure. Once complete the structure contents are freed.
As a result any information in the target channel's connected line information
structure is no longer valid. This change will now set the contents back to a clean
state so that the freeing of the target channel's connected line information structure
when the channel is destroyed will no longer try to double free things.

(closes issue ASTERISK-13906)
