 Hi Bryan,
 
 This failure is caused by a compiler bug that was introduced recently. I don't think the bug is in the Java front-end, but rather is a generic gcc bug that manifests in libgcj.
 
 My workaround is to go back to a 2000-03-30 compiler (using the command "cvs -z9 update -D 20000330 -dP"). You can then update the gcc/java directory to the current version if you wish.
 
 Perhaps you could report this to gcc-bugs@gnu.org - maybe more bug reports will encourage someone to fix it.
 
 regards
