A spot was missed when adapting callers of new_lockspace() to its new (safer, non-pointer) return value. Fixed in changeset 1.1682. Attempted to reproduce, but hit bug 127839. we no longer see this bug but do still see 127839 in comment #2. Updating version to the right level in the defects. Sorry for the storm. |
