Thread: ODBC Compatibility with AMD64

OS: Centos 4 for AMD64 (RHEL 4)<br />PostgreSQL version: 7.4.2<br />PostgreSQL ODBC postgresql-odbc-7.3.8.rpm <br /><br

ODBC.Under x86 platform, this all works find, but under AMD64, we get segment faults during connection. <br /><br />I
amassuming their is an issue with the ODBC driver on this platform because everything else works find on x86 and the
databaseis fine under a native connection.<br /><br />Is there a patch for the ODBC driver to work with a 7.4.x
databaseusing Linux on the AMD64 platform?<br /><br />Thanks.<br /><br />Steve Poe

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.
