# Description
Running mlir-opt --arith-int-range-narrowing on a module containing arith.trunci that truncates to a zero-bit integer triggers an assertion in LLVM's APInt
# Reproduce
mlir-opt version: 22.1.0-rc1
location: If the **arith.trunci** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = arith.constant 42 : i32
%1 = vector.step : vector<4xindex>
%2 = arith.extui %0 : i32 to i64
vector.print %1 : vector<4xindex>
vector.print %2 : i64
%3 = arith.trunci %0 : i32 to i0
return
}
}
```
```
mlir-opt --arith-int-range-narrowing test.mlir
