# Description
Running mlir-opt with the --remove-dead-values pass on a module containing tensor.collapse_shape applied to a DenseElementsAttr triggers an assertion failure
# Reproduce
mlir-opt version: 22.1.0-rc1
location: If the **tensor.collapse_shape** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = arith.constant dense<0> : tensor<i32>
scf.execute_region -> tensor<i32> {
scf.yield %0 : tensor<i32>
}
%1 = arith.constant dense<0> : tensor<2xi32>
%collapsed = tensor.collapse_shape %1 [] : tensor<2xi32> into tensor<i32>
return
}
}
```
```
mlir-opt --remove-dead-values test.mlir
```
```
mlir-opt: /mnt/sdd1/mlir/tool/llvm-project-llvmorg-22.1.0-rc1/mlir/lib/IR/BuiltinAttributes.cpp:1246: mlir::DenseElementsAttr mlir::DenseElementsAttr::reshape(mlir::ShapedType): Assertion `newType.getNumElements() == curType.getNumElements() && "expected the same number of elements"' failed.
