Not sure what is going on here.

According to that bt, it didn't dump core in asterisk code. It failed in
malloc and therefore it would make me question your kernel and/or
system. Also if there is a problem in lintoulaw, you probably would see
a lot of people complaining as I am sure pretty much every one uses that
section of code.
