<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When using an IAX2 peer configured with:
allow=all
Asterisk will segfault when building the peer while loading chan_iax2.so
This is caused by ast_format_cmp trying to compare two ast_format structs using the codec opus format interface defined in res_format_attr_opus. This format interface doesn't define a format comparison function, so when we try to use this undefined function, boom.
The fix for this was to treat an interface without a comparison function in the same manner as we treat comparison with formats that don't have interfaces.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It doesn't crash anymore. That's a start. I also checked the output for the CLI command 'iax2 show peer' for the peer I was using to define all the codecs and that appeared to work alright. Also made a call with just opus and ulaw set as codecs (opus should have been the preferred). Opus ended up not being included in the list of preferred codecs (although output for just Codecs still includes it for some reason) and when making a call the endpoint would choose ulaw.

It gets slightly weirder right now when more stuff is specified after opus...

allow=ulaw
allow=alaw

This is due to a quirk with how we are currently building the codec preferences list and may get resolved by some stuff rmudgett is working on, so this patch just focuses on resolving the crash.</pre>
