I tried with gcc-3.x, and while it doesn't crash - it doesn't work either.
by that I mean that the mote stops sending as soon as TestSerial starts
up (the TX flashes before that, doesn't flash afterwards), and the mote
doesn't react to the data sent by TestSerial either (it should change
it's LEDs AFAIK)
Hmm, trying this on an x86_64 kernel, I did find one bug which is
fixed by the following patch (the change to the Makefile is necessary
to keep Sun's JDK happy at least):

However it's not clear to me that this is the same problem.
