# Description
mlir-opt version: 22.1.0-rc1
mlir-opt crashes when running the --eliminate-empty-tensors pass on IR containing a sparse_tensor.new operation.
# Reproduce
location: If the **sparse_tensor.new** is commented out, the crash no longer occurs.
```
module {
func.func @main() {
%0 = gpu.dynamic_shared_memory : memref<?xi8, #gpu.address_space<workgroup>>
%1 = gpu.grid_dim x
%2 = ml_program.token
%3 = tensor.from_elements %1 : tensor<1xindex>
%4 = tensor.collapse_shape %3 [] : tensor<1xindex> into tensor<index>
%5 = pdl_interp.create_attribute 42 : i32
%6 = sparse_tensor.new %4 : tensor<index> to tensor<1xindex, #sparse_tensor.encoding<{ map = (d0) -> (d0 : compressed) }>>
return
}
}
