asterisk users - Feb 2005 - Segfault when using res_config_odbc on x86_64

I'm trying to move our asterisk setup from an i686 server to an x86_64
(Dual AMD Opteron) server. 

Everything has been manually compiled: MySQL 4.1.10, MyODBC 3.51.11,
unixODBC 2.2.10 (because I couldn't find any usable RPMs). And obviously
Asterisk, where I'm using the STABLE release CVS-Nv1-0-5-02/21/05. The
OS is Redhat Enterprise ES 4.0, kernel 2.6.9-5.0.3.ELsmp.

Asterisk is configured to read sip.conf and extensions.conf from MySQL
via ODBC. The ast_config table contains about 3500 rows.

When I start "asterisk -gcvvvvv" the first time, everything works
fine.
Then I issue a "reload", and something strange happens:


 Reloading SIP
Feb 22 09:50:23 NOTICE[26316]: config.c:764 __ast_load: Loading Config
sip.conf via odbc engine
  == Parsing '/etc/asterisk/res_config_odbc.conf': Found
Use EXIT or QUIT to exit the asterisk console
*CLI> 


After that, basically nothing else happens, and asterisk still works.
Now, if I issue another "reload", asterisk segfaults. That's what
"bt"
says inside gdb:

I'm not sure what the problem could be. What's interesting is that I can
issue "sip reload" or "extensions reload" as much as I want
and it won't
segfault. But two plain "reload"s in a row will crash it.

Anyone?

Thank you
