I agree with Tracy's assesment. Just wanted to add that if your buffer
is too small on FREAD, your stack WILL be corrupted. Depending what
lives after your buffer on the stack will affect the symptoms seen. You
may simply overwrite the next variable defined with a possible 'silent'
failure (no indication this has occured). But I've usually seen that you
eventually get a DMPT (Data Memory Protection Trap). It may not occur
immediately but buffers that are too small is one of the most common
ways to cause a DMPT.
