[issue21584] Unraised overflow error in sqlite3.Row indexing

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

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]
2
>>> 
OverflowError: Python int too large to convert to C long
