The files that were failing for me have chunk sizes set to the maximum value for the field and were not adjusted to the file size when the file was closed.

Fixed with this changeset:

Given certain input WAVE files, the wavread function apparently attempts to allocate way too much memory and causes my system to become unresponsive. The files in question can be opened and played with other programs, so they are valid to some extent. Files originating from Octave's wavwrite do not exhibit this problem.

I'll investigate the details of the files I have that cause this crash.
