# Description
mlir-opt version: 22.1.0-rc1
Running mlir-opt with the --inline pass on an MLIR module containing shape.shape_of on a tosa.const tensor triggers an assertion failure in llvm::cast. The crash occurs when the inliner tries to rewrite the shape.shape_of operation, and the operation’s result cannot be cast to the expected TensorType
# Reproduce
location: If the **shape.num_elements** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = emitc.literal "1" : i32
%1 = "tosa.const"() <{values = dense<1> : tensor<i32>}> : () -> tensor<i32>
%shape = shape.shape_of %1 : tensor<i32> -> !shape.shape
%2 = shape.num_elements %shape : !shape.shape -> !shape.size
return
}
}
```
```
mlir-opt --inline pass test.mlir
```
```
