mlir-opt version: 22.1.0-rc1
The crash is triggered while processing a `memref.generic_atomic_rmw` operation. During lowering to LLVM IR, the pass accesses an internal SmallVector out of bounds, causing a hard assertion failure.
```
mlir-opt --convert-to-llvm test.mlir
```
```
mlir-opt: llvm-project-llvmorg-22.1.0-rc1/llvm/include/llvm/ADT/SmallVector.h:297: T& llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::operator[](size_type) [with T = long int; <template-parameter-1-2> = void; reference = long int&; size_type = long unsigned int]: Assertion `idx < size()' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
