            Bug ID: 49233
           Summary: Assertion  `getOperand(0)->getType() ==
                    getOperand(1)->getType() && "Both operands to ICmp
                    instruction are not of the same type!"' failed

Without turning assertion on, this C program can be successfully compiled
(https://godbolt.org/z/jGjqb4). But it indeed breaks some invariants.
