The following SQL statement will run OK returning a good result.

SELECT ldi_id from ldi_text where obj_id=32118

The following SQL statement will get a segmentation fault.

SELECT * from ldi_text where obj_id=32118

The table has 4 fields  (obj_id int, ldi_id int, ldi_tx_seqnce smallint, ldi_tx_data image)

I have tried this with numerous tables and fields and all queries work OK until I try to query any field with an image datatype.

My configure line for php:
./configure --with-sybase=/opt/sybase-11.9.2 --with-informix=/opt/informix --with-apache=../apache_1.3.12 --enable-track-vars

I now have this working with Apache 1.3.14 and PHP 4.0.3pl1. I have always gotten a Parse error before SQLDA line 273 error in ctpublic.h, whenever I tried to compile --with-sybase-ct using Sybase libraries. Using freetds and the sybase libraries in PHP/extras I always get unresolved references. I finally replaced the ctpublic.h in the Syabse libraries withe the one from the PHP/extras. All compiled and worked fine, including querying for image datatypes. I don't know if these problems were unique to me or not. I finally have a working PHP/Sybase situation.
