Hi Michael,

First sorry for the patchew noise, I didn't meant to sent a patch just an
inlined diff.

For the reproducer, that's pretty straight-forward with v6.0.0-rc5:

$ cat > foo.S << EOF
> __start:
>     wdr
> EOF

$ avr-gcc -nostdlib -nostartfiles -mmcu=avr6 foo.S -o foo.elf
$ xxx/qemu-system-avr -serial mon:stdio -nographic -no-reboot -M mega \
  -bios foo.elf -d in_asm --singlestep
IN:
0x00000000:  WDR

Segmentation fault (core dumped)

Note that I put "--singlestep" here to avoid translating NOPs after the WDR,
it breaks without as well.
