Do not change the OP_String8 opcode into OP_String until *after* any necessary encoding conversions are accomplished. Otherwise, a rerun of the prepared statement after an OOM can result in errors. Test case in TH3. check-in: 8efd6259 user: drh tags: trunk

Fix the instr() SQL function so that it makes a copy of its argument before changing the datatype, since the datatype affects processing. Also fix the sqlite3_value_text() routine so that it always works even for values obtained form sqlite3_value_dup(). Ticket [587791f92620090e] check-in: 3fb40f51 user: drh tags: trunk
