Thanks. Applied & pushed to master.

I split your patch into three commits:

 - avoid freeing the NULL handle

 - ODBMetaDataRS ctor: abort if statement handle allocation failed

 - stop some leaked statement handles

In particular, in the "ODBMetaDataRS ctor: abort if statement handle
allocation failed" commit, I moved the abort (exception throwing) to
the top of the function instead of the bottom. At the bottom, it would
leak the allocation in m_pRowStatusArray, and a reference count in
m_pConnection (because acquire has already been called).

By contrast, the other initialisations done before, in the
initialisation list are safe: no heap allocation :)
