With Clang 15, I get an internal crash in LLVM when compiling this file for source-based coverage:
```C++
#include <vector>
bool unknown_bool();
template <typename RawValT>
class SomeClass {
public:
static std::vector<RawValT> get_test_values() {
return unknown_bool() ? std::vector<RawValT>{RawValT{}} : std::vector<RawValT>{RawValT{}};
}
};
void func() { SomeClass<unsigned short>::get_test_values(); }
```
(This is as minimal of a reproducer as I could muster).
Here is the stack dump:
```
