mlir-opt crashes with an assertion failure when running --convert-arith-to-llvm on a valid MLIR module containing arithmetic operations over dynamically shaped tensors.
```
module {
func.func @main() {
%0 = pdl_interp.create_type i32
%1 = "emitc.variable"() <{value = #emitc.opaque<"">}> : () -> !emitc.lvalue<i32>
%2 = gpu.block_dim x
%3 = shape.const_shape [1, 2, 3] : tensor<3xindex>
%4 = smt.exists {
^bb0(%arg0: !smt.int):
%5 = smt.eq %arg0, %arg0 : !smt.int
smt.yield %5 : !smt.bool
}
%6 = tensor.generate %2 {
^bb0(%arg0: index):
%7 = arith.index_cast %arg0 : index to i32
tensor.yield %7 : i32
} : tensor<?xi32>
%8 = arith.floordivsi %6, %6 : tensor<?xi32>
return
}
}
```
```
