G'day All,

I've upgraded a staging server from Jessie to Beowulf and find a script in my initramfs is now broken, tracking it down it is a huge change in behaviour in the busybox version of dc and I can't find any reference to what I'm missing. Has anyone bumped up against this? I've tried this on both the arm and x64 versions and the behaviour is identical, so it's not an arm thing specifically.

On jessie :
brad@srv:~$ busybox dc
2
2
add
p
4

On beowulf :
root@rpi31:~# busybox dc
2
2
add
p
?

What you can't see at the bottom of the last example is the rendering of the 0x02 character in the shell.

The input processor also appears to have changed.

brad@srv:~$ busybox dc
0x127
p
295

root@rpi31:~# busybox dc
0x127
p
127
