Overview
Comment: | Fix a register allocation problem in PRAGMA integrity_check that caused the same register to be used for two different purposes on the first ATTACHed database if the schema for the ATTACHed database was noticable more complex than the schema for the first database. Fix for ticket [a4e06e75a9ab61a1]. |
