This invalid code will crash on Clang Assertion Trunk.
```cpp
class Foo {
public:
Foo(int);
bool operator==(const int l);
};
#define EQ(x,y) (void)(x == y) // expected-note 6{{defined here}}
void test_EQ() {
Foo F = Foo{1};
EQ(F,Foo{1,2});
}
```
It seems that this goes back to clang-12. The stack dump is very similar to [21755](https://github.com/llvm/llvm-project/issues/21755).
Stack dump:
```
clang++: /root/llvm-project/clang/lib/Basic/SourceManager.cpp:866: clang::FileID clang::SourceManager::getFileIDLoaded(clang::SourceLocation::UIntTy) const: Assertion `0 && "Invalid SLocOffset or bad function choice"' 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.
