--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fixed (dead stmts are no longer "folded" but removed):

Substituting values and folding statements

Folding PHI node: i_1 = PHI <i_2(2), i_3(3)>
Folded into: i_1 = PHI <0(2), i_3(3)>

Folding statement: if (i_1 <= 99)
which is likely CONSTANT
Not folded
Folding statement: i_3 = i_1 + 1;
Not folded
Folding statement: return;
Not folded
Removing dead stmt i_2 = 0;
