If you received a copy of this it is because you have a similar problem
posted on bugs.php.net and I am curious if you have resolved the issue.
Whose issue it, whether it be PHP, Apache, or FreeTDS I don't know.
The following query works properly using FreeTDS 0.51 and the one below it
does not(it cause apache to segfault). BOTH queries however both work when
using ODBC(--with-esoob).
I have tried recompiling all three parties; FreeTDS, php4.0.3pl1, and apache
1.3.14-ssl. I have also tried switching between TDS versions 4.2, 5.0, and
7.0, which doesn't really seem to make any change. The server I am
attempting to chat with is a MS SQL Server version 7.0. It does not have
any service packs, I realize that this may be a problem or the problem
itself, but I am curious as to why it would not cause a segfault with the
other queries I am doing. I have also removed GD support, etc.
