Hi Dave,

Does this sound like a bug, it need right shift of the subtraction result,

crash-git> pd (678324157984276 >> 32)

$10 = 157934

crash-git> pd ((681670518181331-678324157984276) >> 32)

p: gdb request failed: p ((681670518181331-678324157984276)

crash-git> 

It might be lacking support of some advanced arithmetic, so what is a proper way

to do some arithmetic like this?
