MLIR built at commit https://github.com/llvm/llvm-project/commit/4b815d84
Reproduced with:
`mlir-opt --inline temp.mlir`
temp.mlir:
``` milr
module {
func.func @func() {
%c0 = arith.constant 0 : index
%alloc = memref.alloc() : memref<8xf32>
scf.index_switch %c0
default {
%0 = bufferization.clone %alloc : memref<8xf32> to memref<8xf32>
%1 = memref.realloc %0 : memref<8xf32> to memref<15xf32>
memref.dealloc %1 : memref<15xf32>
}
memref.dealloc %alloc : memref<8xf32>
return
}
}
```
trace:
```console
Assertion failed: (op->use_empty() && "expected 'op' to have no uses"), function eraseOp, file PatternMatch.cpp, line 276.
