Can you try a newer compiler such as 3.3.3? (please do not attach the .class file as it is copyright and 
you cannot distribute it).

Does this still happen in a newer compiler, 3.4.0 also just released with a huge amount 
of bug fixes fro GCJ, Can you try 3.4.0?

I could not find "java/text/Normalizer" in the current JDK 1.4.2.03 on 
Linux-x86, but I did find "sun/text/Normalizer" which does indeed cause
mainline GCJ to ICE like so:

No response from reporter. GCJ does not support compilation of the Sun class
libraries, and GCJ developers can't debug problems with Sun class libraries
because looking at those class libraries may contaminate us. I'm closing this bug.
