    The following program produces an assert failure with a `clang` binary built with assertions, when compiled with `-fblocks`:

```cpp
template<typename... Ts>
struct Cls {
 static_assert([] consteval -> void {
    (^Ts);
 });
};
```

The assertion:
```
Assertion failed: ((!Unexpanded.empty() || Visitor.containsFunctionParmPackExpr()) && "Unable to find unexpanded parameter packs"), function DiagnoseUnexpandedParameterPack, file SemaTemplateVariadic.cpp, line 467.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

clang++: error: unable to execute command: Abort trap: 6
clang++: error: clang frontend command failed due to signal (use -v to see invocation)
```

Here is another example that fails the same assertion:
```cpp
template <typename... Ts>
void fn(int = [] consteval -> int { (^Ts); return 0; }());
```

Both have the same root cause:
1. While parsing the `CompoundStmt` body of the lambda, clang begins to parse `^Ts` as a `BlockExpr`.
2. The `Sema::ActOnBlockArguments` function invokes `DiagnoseUnexpandedParameterPacks`, which sets `LambdaScopeInfo::ContainsUnexpandedParameterPacks` to `true`, prior to recognizing that the `BlockExpr` is ill-formed.
3. The ill-formed `BlockExpr` is diagnosed, and is subsequently discarded from the `CompoundStmt` representing the body of the lambda.
4. The `LambdaScopeInfo` is used to initialize the `LambdaExpr`, resulting in `LambdaExpr::ContainsUnexpandedParameterPack` being set to `true`.
5. The `LambdaExpr` becomes an argument to some other semantic construct (e.g., `StaticAssertDecl`, `ParameterDecl`), whose semantic analysis calls `DiagnoseUnexpandedParameterPack`.
6. The above assertion triggers because the `LambdaExpr` reports that it contains an unexpanded parameter pack, but the tree walk fails to find any pack (since the ill-formed `BlockExpr` was discarded from the `CompoundStmt`).

Although I can imagine a few ways to patch this (e.g., keep an "error" representation of the ill-formed `BlockExpr` in `CompoundStmt`, rollback the setting of `LambdaScopeInfo::ContainsUnexpandedParameterPack` when the `BlockExpr` is ill-formed, just remove the assertion from `DiagnoseUnexpandedParameterPacks`), I'm not sure I love any of them. For now, I figured I'd just report the issue.
