The problem is in the register allocator. What happens is that after register
allocation, we have something like:
r27:DF = [r11:SI]
...
r27:SI = 0
...
and then the first def gets deleted because it's obviously dead code. I don't
know why the register allocator chooses r27 for the SImode pseudo.
Scheduling is necessary to trigger the bug, but it's not the problem.
