a78d757c36 Fix the sqlite3_column_decltype() interface to return the correct datatype 
when the value comes through a CTE.

e2463398fd The simplification to sqlite3SelectExpand() in last night's 
[3a4ffb21] check-in was not completely correct.  This adjustment is needed
for correct OOM handling in some configurations.

an SQLITE_CORRUPT return before the memmove() is reached.
