    **This testcase is generated by a fuzzer.**

Compiler explorer: [https://godbolt.org/z/sEWPGr146](https://godbolt.org/z/sEWPGr146)

This invalid code will crash on Clang Assertion Trunk:
```cpp
struct bar {};
enum T : int { bar = 1, };
struct R {
  void set(bar 
#pragma message "Any Message"*);
};
void R::set(bar *val) {}
```

It seems that this goes back to clang-6.

Stack dump:
```
clang++: /root/llvm-project/clang/lib/Sema/SemaAccess.cpp:758: AccessResult HasAccess(clang::Sema&, const {anonymous}::EffectiveContext&, const clang::CXXRecordDecl*, clang::AccessSpecifier, const {anonymous}::AccessTarget&): Assertion `Access == AS_private || Access == AS_protected' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
