When integer index overflows C long, sqlite3.Row.__getitem__() doesn't raise an exception. Instead overflow exception is raised later.

>>> import sqlite3
>>> con = sqlite3.connect(":memory:")
>>> con.row_factory = sqlite3.Row
>>> row = con.execute("select 1 as a, 2 as b").fetchone()
>>> row[2**1000]
OverflowError: Python int too large to convert to C long

Actually this happens after applying the patch from issue10203.
