[Bug tree-optimization/26358] -ftree-vrp generates invalid code with this loop that overflows integer multiplication

--- Comment #2 from tomfelker at gmail dot com 2006-02-19 02:20 --- OK, -fwrapv fixes it. But what if I do this, shouldn't it work as I expect? (It doesn't without -fwrapv.) Also, what is the safe way to do what I want? int min = INT_MAX, i; for(i = 1; i > 0; ++i)
