Hi I was wondering if anyone could shed some light on why Kaffe is eating it
on sparc-linux 2.0.33 glibc... 

Running the HelloWorldApp I crash giving me this info in gdb:

(gdb) disassemble $pc
Dump of assembler code for function __kill:
0x500eadd4 <__kill>:    mov  0x25, %g1

End of assembler dump.

This was built from the snap last night and the only changes are
with the config/sparc/linux/md.h where this was added:

#undef SP_OFFSET
#define SP_OFFSET 0

Thanks for anyhelp any one can give
