I'm using psqlodbc-08.00.101 with two patches applied:

<http://archives.postgresql.org/pgsql-odbc/2005-03/msg00126.php>
<http://archives.postgresql.org/pgsql-odbc/2005-03/msg00038.php>

Neither of these patches fix a problem which would cause a crash.

Long ago I submitted a patch to unixODBC which fixed a
freeing-the-same-memory-twice bug. This caused a crash when
disconnecting from the database in 64-bit, but not in 32-bit. This was
in unixODBC-2.2.8; recent unixODBC should not have this problem.
