<pre>Example: <a href="https://godbolt.org/z/q45aMxMnE">https://godbolt.org/z/q45aMxMnE</a>
Using an `exclusive_trylock_function` in a boolean expression causes
-Wthread-safety-analysis to warn that the lock "is not held on every path
through here".
This seems like either a false positive or false negative.
I thought it was the former, as I found it in an expression similar to
`m.TryLock() || Exit()`, where `Exit()` is a noreturn function that calls
`exit()`.</pre>
