[vrogier]

OCI_TypeInfoGet() creates a OCI_TypeInfo object, add it to the list of OCI_TypeInfo object for the given connection, populates it with data retrieved from Oracle OCI client then returns it to the caller.
Since v4.7.4, in case of error while retrieving data from Oracle, the created OCI_TypeInfo is not removed for the connection internal list.
Leading a second call to OCI_TypeInfoGet)( to return an incomplete instance of OCI_TypeInfo.
