ID: 20935 Comment by: bds at geekboys dot org Reported By: jonas at ionax dot se Status: No Feedback Bug Type: MSSQL related Operating System: RedHat Linux 7.2 / Apache 1.3.27 PHP Version: 4.3.0 New Comment: With this setup: PHP Version 4.3.0 Red Hat 8.0 (Linux 2.4.18-3) Apache 1.3.27 FreeTDS 0.60 It worked fine with --with-mssql In this setup: PHP Version 4.3.1 Red Hat 8.0 (Linux 2.4.18-14) Apache 1.3.27 FreeTDS 0.61 I had to compile with --with-sybase to get it to work. Exact same installation routine on both systems.

I'm using the MSSQL function anyway. Greettings. Ernesto ------------------------------------------------------------------------ [2003-01-27 09:46:09] ernesto at gupos dot com dot ar It doesn't seemd to be a FreeTDS bug. I tested the tarball and CVS version of FreeTDS with sqsh (a command line client that use FreeTDS library, www.sqsh.org) and it worked fine. But, when I do a remote connect with PHP using the same FreeTDS library, it segfault when I do a simple: $res = mssql_query("select * from Test"); The connection and selection of the database works fine. That's all that I can say for now. Thanks for all.

To my knowledge the latest version of that is 0.60! - Frank ------------------------------------------------------------------------ [2003-01-21 07:56:03] jonas at ionax dot se recompiled as cgi but still generates the same error.
