Hmm. The difference is in the conversion of an integer value larger than
2^31, to a C type that's not large enough to hold it. According to the
ODBC spec, that's supposed to raise an error, sqlstate 22015, and the
result is undefined.
(http://msdn.microsoft.com/en-us/library/ms712567%28v=vs.85%29.aspx)

I actually removed those particular test cases after the 09.03.0400
release, when I added tests for large objects. The above OID conversion
tests started to behave differently after the "lo" domain, for large
objects. So the issue should be resolved in git master already, by accident.

The real issue here is that the driver doesn't raise an error when a
numeric value's whole part is truncated.
