# Description
mlir-opt version: 22.1.0-rc1
Running mlir-opt with the --convert-vector-to-llvm pass on a module containing a vector.insert with an index exceeding the outer vector dimension triggers an assertion failure
# Reproduce
location: If **vector.print %2 : vector<2x4xi1>** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = vector.constant_mask [1, 4] : vector<2x4xi1>
%1 = arith.constant 257 : index
%iv = vector.extract %0[0] : vector<4xi1> from vector<2x4xi1>
%2 = vector.insert %iv, %0[%1] : vector<4xi1> into vector<2x4xi1>
vector.print %0 : vector<2x4xi1>
vector.print %2 : vector<2x4xi1>
return
}
}
```
```
mlir-opt --convert-vector-to-llvm test.mlir
```
```
mlir-opt: /mnt/sdd1/mlir/tool/llvm-project-llvmorg-22.1.0-rc1/mlir/lib/Dialect/Vector/IR/VectorOps.cpp:362: mlir::vector::getAsIntegers(llvm::ArrayRef<mlir::OpFoldResult>)::<lambda(mlir::OpFoldResult)>: Assertion `isa<Attribute>(foldResult) && "Unexpected non-constant index"' failed.
