This is caused by caching a pointer and reference to the data cache's
IPersistStorage interface without managing reference counts
appropriately.

ole32: Fix a typo in PropertyStorage_WritePropertyToStream that caused the wrong data to be written to the stream.

The field pClipData is a pointer to the data to be written, not the start of it.

This behavior was discovered by Huw Davies.

Make sure that mixing table columns returns the expected
data. eg:  SELECT t1.action, t2.action FROM t1, t2
should return distinct data.

Propagate tablename from 'SELECT tablename.column from tablename' queries
into VIEW_find_column(). Previously, the tablename had been dropped.

This makes cleanup after errors much easier, as we can just use the regular
destructor.

The parameter controls whether weak references are ignored, not
whether the last stub_manager_int_release should be called when the
total reference count goes to zero.
