After building a new web server and pulling my content over from its
predecessor, I'm having a strange problem with some of my PHP scripts.
I'm not certain it's a freetds bug, but I have a hunch that it is.
Here's what's happening:

* PHP scripts containing certain queries are segfaulting unless I
comment out the odbc_result() calls to certain fields in the query
results.  
* The fields only break the queries if they are non-null - querying
records with null values in those fields works fine
* The fields in question don't have much in common.  Some are varchar,
some are text...
* If I run the same query through isql without involving PHP or the web
server, it runs fine! BUT...
* If I try it in tsql, it fails with this message:

Msg 4004, Level 16, State 1, Server VOYAGER, Line 1
Unicode data in a Unicode-only collation or ntext data cannot be sent to
clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier.

* Tsql runs the queries fine if I remove all references to ntext fields.
BUT...
* The ntext fields that tsql objects to are NOT the fields that I find
are breaking in the PHP scripts.

Here are the specs of my server:
AMD-64 
2GB RAM (over 1GB shows free at the moment)
CentOS 4.4 for x86-64
freetds 0.64 built from source, configured with manual reference to the
location of unixODBC
unixODBC 2.2.11 built from source
php 4.3.9-3.22
Apache 2.0.52-28 ent.centos4

And I'm connecting to MS-SQL 2000 on a Windows SBS 2003 box.  

Here's the relevant section of odbc.ini:
[Voyager]
DRIVER          = /usr/lib/libtdsodbc.so
DESCRIPTION     = SQL Server 2000 on Voyager
TRACE           = no
SERVER          = voyager.experienceplus.com
APP             = FreeTDS/unixODBC on WWW2
UID             = xxxxx
DATABASE        = XPlus
PORT            = 1433
TDS_VERSION     = 8.0

And here's the relevant stuff from freetds.conf:
[global]

        tds version = 4.2

;       initial block size = 512

;       swap broken dates = no
;       swap broken money = no

;       dump file = /tmp/freetds.log
;       debug flags = 0xffff

;       timeout = 10
;       connect timeout = 10

        text size = 64512
[Voyager]
       host = voyager.experienceplus.com
       port = 1433
       tds version = 8.0

Anyone who has insight into this problem will earn my gratitude and a
virtual pat on the back. Thanks,

(and by the way, are the semicolons in freetds.conf comment characters?)
