[Matthew T. Kromer]

Update of /cvs-repository/Products/DCOracle2/src
In directory cvs.zope.org:/tmp/cvs-serv8571/src

Modified Files:
	dco2.c 
Log Message:
Mihai Ibanescu points out that if you do a cursor.prepare() followed by a 
cursor.describe(), you segfault.  This is not a normal code path, but segfaults
are still bad.
