I need to access a MS-SQL server 2000 from a linux RH7.1 box running PHP 4.1.1 compiled with the following options:
./configure --with-sybase=/usr/local/freetds --with-apxs
And freetds installed from RPM (but I also tried with the source and it didn't work either... tried FreeTDS from CVS as well). and apache 1.3.19.
PHP seems to be working fine and phpinfo(); seems fine...
Whenever I load a PHP script that uses any mssql_* function, the page cannot load "The page cannot be displayed"...
When I check apache's error log, it reports Segmentation Fault on child process.
I tried with different versions of PHP and it always crashes the same way but the Perl applications using FreeTDS to connect to the same server work just fine so it probably is a problem related to PHP.

Any input ?

please read

Once you have generated a backtrace, please submit it to this bug

Well I tried the same thing with another configuration and it seemed to be working so I think it might be an apache related problem.

I will upgrade to the latest version of Apache in the next week or so so I will get a backtrace then if the problem persists.

Thank you.

Okay well now I upgraded to apache 1.3.20, and php 4.1.2 and freetds 0.53, I don't even get as far as the segmentation fault anymore because after compiling PHP with:
./configure --with-apxs --with-sybase=/usr/local/freetds --with-pspell
and make and make install, apache doesn't seem to be running anymore, I do /etc/rc.d/init.d/httpd restart and the following message appears:
Starting httpd: Syntax error on line 260 of /etc/httpd/conf/httpd.conf:
Cannot load /etc/httpd/modules/ into server: /etc/httpd/modules/ undefined symbol: dbdead    [FAILED]

I could not find a way to solve this problem.

After formatting the server and reinstalling redhat latest version, I am not experiencing the problem anymore, it seems it was a redhat configuration issue more than a PHP related problem.
