What version of libsndfile?

Are you sure the array you are reading into is large enough? Both the
files in tha tar.bz2 file were stereo. When you read a stereo file with
sf_readf_float, and ask for N frames, the destination array must be 
2 * N in size.

Audacity and Sweep both use libsndfile for file I/O.
