The following is the gdb backtrace of the crash (which I can reproduce every time i click the 'reload' button in my browser).
I'd be happy to send the scripts to you (there are several of them that work together, since each object is in it's own script file).
I have been having some other strange problems like trying to free mysql result resources or close mysql connections and getting warnings that those link or resource id's are not valid.

Here's the vital statistics:
OS: RedHat i386 Linux 7.1 with all updates applied from RedHat
MySQL: 3.23.38-1 (RPM from mysql.com)
Apache: 1.3.20, compiled locally (--enable-module=so)
PHP: 4.0.5 compiled/linked against mysql and apache as a DSO (--with-apxs=... --with-xml --with-mysql)
I'm using a standard configuration file with one change: the 'include_path' has been set to include the scripts necessary for my application. There are no path conflicts (that is, the file X.php does not exist relative to the executing script AS WELL AS in the include_path).

Thank you for your time.

Does this happen with PHP 4.0.6 ?
 [2001-07-02 09:08 UTC] schultz at adrenaline dot com 
Honestly, I haven't tried it. After the problems we had with 4.0.5, our client (and I) decided to move to the more familiar territory of Java. I believe that I still have a setup on which I could test 4.0.6 beta, so I'll try to get to that this week. I'll post something as soon as I know.

Thanks for your time,

Any update on this?
 [2001-11-26 08:06 UTC] schultz at adrenaline dot com 
sorry, there's no update from me.

I haven't had the time to install the later version and test. I'm actually working onsite with my client, now, and have the PHP installation and code back in my office which I haven't seen for months.

If someone needs to close-out this bug, mark it as "Won't fix" or "Unconfirmed", and I'll try to get it when I get back in the office. That won't be for a few months, though.
