Subject: Fix a faulty assert() statement - adding a CORRUPT_DB term - based on a test
X-Git-Tag: version-3.37.2~11
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=48b9d1768051dfd15559c326731d40e7b5a7c68a;p=thirdparty%2Fsqlite.git

Fix a faulty assert() statement - adding a CORRUPT_DB term - based on a test
case derived from [562805cf488a455c].  Also add a test case to that prior
issue.
