When using mlir-opt with the **--convert-complex-to-libm** flag, the compiler crashes with an assertion failure in the arith dialect's folding logic. The crash occurs when **arith.addui_extended** operates on a **ub.poison** value, as the folder fails to handle non-typed attributes correctly during the casting process.
```mlir
module {
func.func @main() {
%0 = "tosa.const"() <{values = dense<0> : tensor<1xi32>}> : () -> tensor<1xi32>
%1 = ub.poison : tensor<1xi32>
%2, %3 = arith.addui_extended %0, %1 : tensor<1xi32>, tensor<1xi1>
return
}
}
```
```
mlir-opt --convert-complex-to-libm test.mlir
```
```
mlir-opt: llvm-project-llvmorg-22.1.0-rc1/llvm/include/llvm/Support/Casting.h:566: decltype(auto) llvm::cast(From&) [with To = mlir::TypedAttr; >From = mlir::Attribute]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' 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.
