The bug is there in the v0.5.0 version of sparse but not trigger-able. That is until Luc submit some patch kill dead bb and dead instructions which make the bug trigger-able. There is a revert on sparse-next to temporary stop the bug, by just revert some change that Luc introduced. The change itself is fine and remain on RC5, it just make the bug trigger-able as side effect. The real fix is submitted by Luc later. > I ran the test case kill-unreachable-phi.c in my repository and did > not see an infinite loop.
