Subject: Change loop counter variables from int to i64 to avoid a potential
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2f5d281796853250befde5f83dfe8b909c4a5b39;p=thirdparty%2Fsqlite.git

Change loop counter variables from int to i64 to avoid a potential
integer overflow inside an assert() statement when SQLite is compiled
with SQLITE_DEBUG and an extra-large SQLITE_MAX_LENGTH.  Does not
affect production builds.
