 I've confirmed this bug report using
 gcj (GCC) 3.4 20021230 (experimental).

 I have a shorter test case that reproduces this bug (see the 
 attachement). The bug is still there as of gcj 3.2.1 (the location of 
 the internal compiler error is now expr.c:2769).
 
 It seems that the implementation of either 'swap' or 'dup_x1' is bogus. 
 This is a stopper for my using gcj at the moment. Can anybody help?
 
 Daniel

 I looked at this today.  I agree the bytecode is fine.
 The problem is that gcj, in java/expr.c, is using emit_move_insn to
 try to emit a move between two items with different modes.  This is
 invalid.  I don't know enough to suggest a fix though :-(

Gcj emits an internal error while compiling

The code is not generated by javac but nicec (a different

Therefore I cannot provide a java source file.
