App crash on iOS related to unpacking vorbis

Question

My iOS application is consistently crashing with an EXC_CRASH reason. After symbolicating the crash report, I found this offending line in the stack trace of the crashed thread:

vorbis_book_unpack(oggpack_buffer*, CAkVorbisAllocator&, int) (in <my_app_name>) (codebook.cpp:1615)

I don't have access to this .cpp file so I'm hoping somebody here can explain why this Wwise code might be crashing my application.

Thanks!
