To Artifact [ebad891b]:

• File src/where.c — part of check-in [d5513dfa] at 2014-04-03 16:29:31 on branch trunk — Use OP_Copy instead of OP_SCopy when moving results out of a subquery, to prevent the subquery results from changing out from under the outer query. Fix for ticket [98825a79ce1456]. Problem introduced by check-in [1e64dd782a126f48d78]. (user: drh size: 223450) [more...]
