I got this crash when I was listening to an iTunes-encoded ALAC file. I can't reproduce it AFAICT.

For the record, my OS is WinXP SP2 and my processor is a P4. If more info is needed, just ask.

I've added a simple fix so read access violations in ALAC decoder don't crash foobar2000 process. It would be interesting to see if the file that crashed produces output bit-identical to what it was encoded from when it doesn't crash.
This ALAC decoder code is horrible, I have no interest or free time to fix it; it will be most likely dropped from the setup and made available separately.

This post show an ALAC decoder version 1.0. I've only been able to find version 0.0.2. Where can I find the more recent version? Thanks very much.
