Given the following file, utils.H:
```
#include <unavailable_header.H>
void getUncrossPrice()
{
if (unavailable)
{
function1(uncrossPrice);
}
else
{
function2(uncrossPrice);
}
}
```
**I've reduced this test case down as far as I could. Removing any other aspect makes the warning stop appearing.**
I get the following warning:
```
clang-tidy utils.H -checks="bugprone-branch-clone"
Error while trying to load a compilation database:

Found compiler error(s).
```
What I would expect is for `clang-tidy` to report the errors, but not the warning.
This is on clang-tidy v13.0.0.
I'd be happy to try to fix this, if confirmed.
