How can I set the status of this tracker to CONFIRMED ?
Should'nt the component be "tree-optimization" instead of "middle-end" ?

This seems to be a possible fix.
What do you think of it, Jan?

Summary:
tree-ssa-loop-im.c moves code, out of an if statement inside the loop
it it can not cause side effects or faults, but it does not care of integer
overflows. this seems to be an optimization!

Andrew, because of short-circuiting, when p >= 0, the expression "-2147483647 -
1 - p" isn't actually evaluated.
Thanks for looking into this so quickly!

-2147483647 - 1 - p
Hmm, this overflows for p > 1.
