At the moment I'd recommend using the latest release rather than CVS as
the code in CVS is undergoing a number of reasonably major changes, and
so won't be as stable as the release.

This is where the problem occurs I think - looks like your queuelen is
getting corrupted somehow. The standard cause of this is more than one
thread operating in the stack at the same time. lwIP is not thread
safe, and so needs protection in this sense.
