13:24
When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. check-in: 3dda3c93 user: drh tags: trunk

In the OP_Column opcode, when extracting a field that is past the end of a short record (because the row was originally inserted prior to ALTER TABLE ADD COLUMN) then make sure the output register is fully NULL and does not contain leftover flags (such as MEM_Ephem) from its previous use. Fix for ticket [43107840f1c02]. This is a cherrypick of check-in [24780f8ddc1683fc]. check-in: 304ea6ba user: drh tags: branch-3.8.7
