It would be nice if you can provide a backtrace
too - who knows, maybe you can debug it yourself
too. ;-)

Get a recent GDB (6.2 or 6.2.1) and use "debugx"
from:

  http://gcc.gnu.org/ml/gcc/2004-03/msg01195.html

to run your testcase like so:

  debugx jc1 gcj <rest-of-the-command-line>

Inside GDB, "run" and then "bt" when you get the
ICE - you know the drill...

(This assumes that you've compiled GCC yourself
and have the sources lying around.)

HTH,
Ranjit.
