I used MLIR to analyze the following program and triggered a crash bug.
### Input Program
```llvm
module {
func.func @main(%arg0: tensor<4x4xf32>, %arg1: tensor<*xf32>, %arg2: tensor<*xf32>, %arg3: tensor<2x3xi32>, %arg4: tensor<2x3xi32>) {
%c1 = arith.constant 1 : index
%0 = llvm.mlir.constant(0 : i32) : i32
%1 = llvm.mlir.poison : vector<128xi32>
%2 = llvm.mlir.constant(1 : index) : i64
%3 = llvm.mlir.constant(dense<3.40282347E+38> : vector<128xf32>) : vector<128xf32>
%alloc = memref.alloc() {alignment = 64 : i64} : memref<4xf32, #spirv.storage_class<StorageBuffer>>
%5 = builtin.unrealized_conversion_cast %alloc : memref<4xf32, #spirv.storage_class<StorageBuffer>> to !llvm.struct<(ptr, ptr, i64, array<1 x i64>, array<1 x i64>)>
gpu.launch blocks(%arg5, %arg6, %arg7) in (%arg11 = %c1, %arg12 = %c1, %arg13 = %c1)
threads(%arg8, %arg9, %arg10) in (%arg14 = %c1, %arg15 = %c1, %arg16 = %c1) {
// ...
gpu.terminator
}
return
}
}
```
### Crash Log
```bash
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
