----------------------------------------

Unfortunately, there's still a large number of symbols that aren't in your libraries:

We'll really need the debug symbols in everything to find out what is actually occurring.

That aside, it is exceedingly odd to see something crashing in a format comparison. What format modules are you using? Are they compatible with the version of Asterisk that you're using?
