Well, I've stopped the crashing.

It was my bad, but still a bit confusing.

Here's what I was doing


       samples=info->frames*info->channels;
       sound=(sample_t *) malloc (samples * sizeof(sample_t));
       sf_readf_float(f,sound,samples);

Which (I now realise) isn't quite right because I'm trying to read
twice as many frames as there are in the file (assuming a stereo
file).  

Changing to sf_read_float does the trick, but I still don't understand
why some stereo files worked, while others didn't.  Opening them in
something wlse and saving them again in exactly the same format made
them work!

Also, shouldn't sf_readf_float handle being asked to read too many
frames?
