System: NetBSD aquila 2.0G NetBSD 2.0G (AQUILA) #1: Sat Aug 7 11:44:23 MEST 2004 mlelstv@pepew:/home/mlelstv/NetBSD-current/obj.sparc64/sys/arch/sparc64/compile/AQUILA sparc64
Architecture: sparc64
Machine: sparc64
>Description:
	trying to cross-build an Amiga release on the above system, I tripped
	over a bus error of elf2bb. Basically Sparc64 is picky about
	alignment and doesn't like some of the assignments made.
>How-To-Repeat:
	try to compile and use elf2bb on sparc64
