Invalid Page Fault in PSQLODBC.DLL

Whenever I try to access a Postgresql database from Visual Basic 6.0
with a Data Control or a Remote Data Control, the program crashes with
an invalid page fault error such as the one below.

  USER caused an invalid page fault in
  module PSQLODBC.DLL at 0247:10012923.

The server is Postgresql 7.0.2 running on Debian Woody.  The same
problem appears with the psqlodbc.dll versions 6.50.0000 from
ftp.postgresql.org and version 7.01.00.01 from Great Bridge.

Accessing a non-psqlodbc DSN with the same data in the same table with
the exact same controls and settings works fine.

Below is the log file generated by the Great Bridge version of the
driver, using the Remote Data Control.  I can post the other logs as
well if they would be useful, but they are quite similar, and they all
end after the last column is listed in the SQLColumns section.

Is there a bug in the driver, or am I doing something wrong?  I would be
more than happy to do any further tests neeeded (I have both cygwin and
a full Visual Studio 6.0 installation on this machine).

Thank you very much in advance.
