# Description
mlir-opt version: 22.1.0-rc1
mlir-opt crashes when running the --tosa-infer-shapes pass on IR containing a tensor with unknown rank (tensor<*xi32>), such as the output of tensor.cast from tensor<1xi32>.
# Reproduce
location: If the **tosa.avg_pool2d** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = gpu.block_id x
%1 = "tosa.const"() <{values = dense<0> : tensor<1xi32>}> : () -> tensor<1xi32>
%2 = tosa.reduce_sum %1 {axis = 0 : i32} : (tensor<1xi32>) -> tensor<1xi32>
%3 = tosa.bitwise_or %2, %2 : (tensor<1xi32>, tensor<1xi32>) -> tensor<1xi32>
%4 = tensor.cast %3 : tensor<1xi32> to tensor<*xi32>
%5 = tosa.avg_pool2d %4, %1, %1 {acc_type = i32, kernel = array<i64: 1, 1>, pad = array<i64: 0, 0, 0, 0>, stride = array<i64: 1, 1>} : (tensor<*xi32>, tensor<1xi32>, tensor<1xi32>) -> tensor<*xi32>
return
}
}
