Overview

Comment:	Avoid a harmless reference to an uninitialized variable following an error in FTS3. This is not a bug. The change is to silence a valgrind warning.

Context

2011-10-27
15:19		If an error occurs within sqlite3_step() on a statement prepared using sqlite3_prepare_v2(), transfer both the error code and error message to the database handle before sqlite3_step() returns (so that they are available via sqlite3_errcode() and sqlite3_errmsg(). Prior to this commit, only the error code was transfered. The error message was not available until after either sqlite3_reset() or sqlite3_finalize() had been called on the statement handle.
