The new commit message is the following:

|
| `snap_usedef()` analysis doesn't check slots for child upvalues of the
| currently recorded function in use-def analysis. Hence, such slots may
| be considered unused and not stored in the snapshot. So on snapshot
| restoration, values from these slots may be lost.
|
| This patch adds a marking for all such local upvalues.
