Ah, I have found the cause of the crash, and added documentation about
the cause:
On Win32, if the <application>ecpg</> libraries and application are
compiled with different flags, this function call will crash the
application because the internal representation of the <literal>FILE</>
pointers differ.
While such a mismatch is a problem on all platforms, it is more common
on Win32 where the FILE structure changes for debug, for example.
