Malcolm Davenport commented on ASTERISK-20727:
----------------------------------------------

I'm on PIAF 2.0.6.2.4 64-bit, because it was the current version, on a VirtualBox instance.
I installed "brown" and opted for FreePBX 2.10.  It gave me Asterisk 1.8.11-cert8.
I did the install-digiphones.  That installed a really old res_digium_phone, so I downloaded the current res_digium_phone 1.3.0 for x86_64 and put the .so in place and restarted amportal.  
I used the FreePBX Digium phones module that came with install-digiphones.  Someone was asking me separately about using a newer version, so I grabbed the SRPM off our download site, installed it, unpacked it into the digium_phones freepbx module directory and then through the FreePBX module admin updated it.  I'm at version 2.10.0.7.tar.gz.

I've got two phones tied to the system now and I've done hundreds of "core reloads" without issue.

I'll leave it to someone else to look at backtraces, but towards reproducing, I'd like to know what versions of everything else and what platform (base system?  VirtualBox?  proxmox?) you're on.

> When freepbx issues a core reload or a manual core reload is issued asterisk crashes with "segfault at 0000000000000150 rip 0000000000483b50 rsp 0000000045f97d90 error 4" or similiar. I cannot reproduce when res_digium_phone.so is unloaded. I've tried debugging using methods described including valgrind. However I could not get the module to load when I recompiled with DONT_OPTIMIZE, DEBUG_THREADS, MALLOC_DEBUG.
