Bus error during itdb_parse

We're using libgpod 0.8.0 a very small number of users have had crashes with the stack traces below. I've given multiple examples of the call stack that leads to it, but the crash seems to be when accessing data from a file that libgpod has mapped into memory. The exception is always a bus error and the platform is always Mac OS X. The problem seems to be 100% reproducible for the affected users. Unfortunately, we're receiving crash reports anonymously, so we are unable to contact the users for more information.

I've spent some time looking through the libgpod source. I was not able to track down anything that seemed to be causing this problem. If anyone has any ideas on what could cause this error, I'd be more than happy to continue looking into it.
