    Test on commit: https://github.com/llvm/llvm-project/commit/e0282cb4da9402de5712ac7855af6c71a03d0c19
The same crash occurred in [LLVM 16](https://github.com/llvm/llvm-project/tree/release/16.x)


```
mlir-opt test.mlir
```
The test case is a function in [pretty_printed_region_op.mlir](https://github.com/llvm/llvm-project/blob/release/16.x/mlir/test/IR/pretty_printed_region_op.mlir)：
```
func.func @pretty_printed_region_op(%arg0 : f32, %arg1 : f32) -> (f32) {
  %res = test.pretty_printed_region %arg1, %arg0 start special.op end : (f32, f32) -> (f32) loc("some_NameLoc")
  return %res : f32
}
```
crash trace:
```
LLVM ERROR: special.op created with unregistered dialect. If this is intended, please call allowUnregisteredDialects() on the MLIRContext, or use -allow-unregistered-dialect with the MLIR tool used.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
