Subject: Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined
X-Git-Tag: version-3.7.5~69
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4278d53efa42707c253fee9420c53e760307f17b;p=thirdparty%2Fsqlite.git

Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined
and the constant folding optimization is disabled using sqlite3_test_control().
Problem introduced by [ad8bc68197f2b4] but we missed it prior to the 3.7.4
release due to taking shortcuts and skipping tests in the release checklist.
