_unsafePerformance triggers "Generic function calls can cause metadata allocation or locks"

Using Swift
1

I am trying to get the following pattern to work with @_noLocks:

@_noLocks
func test(execute: () -> Void) {
    execute()
}

This works:

test { 1 + 1 }

But this doesn't work:

test {
    _unsafePerformance { _ = 1 + 1 }  ❌ Generic function calls can cause metadata allocation or locks
}

This is only happening if _unsafePerformance is called from a closure that I pass in and not directly from test.
