fixes #24274 The code in the `if` branch replaces the current destination `d` with a new one. But the location `d` can be an assignment location, in which case the provided expression isn't generated. To fix this, don't trigger this code for when the location already exists. An alternative would be to call `putIntoDest` in this case as is done below.
