Bug Type: MySQL related
Operating System: Linux kernel 2.4.20-pre5
PHP Version: 5CVS-2003-01-26 (dev)
New Comment:
Magnus,
You asked for a backtrace. Whenever I start gdb it only shows a blank
page (body and html tags, nothing more). I normally start apache with
apachectl startssl but gdb doesn't like that.
Sorry.
Regards,
Hans

K, hear it is:
class.Session.php is a session save handler which stores the session
data within a database (mysql). As soon as mysql_fetch_objects is used
it barfes. This is in both classes and in procedural functions.
The code works fine on the same machine when php4.X is used.
Let me know if you want more information.
Regards,
Hans

Backtrace for example would be nice, and a small reproduce
script. I've tried this and could not reproduce it.

Well, afaik only the information regarding what I expected is missing.
Then again, using mysql_fetch_object is rather obvious I think. Maybe
the platform is important too? (x86)
Could you give me a little more hints on what you expect?
Regards,
Hans

I've ran into some problems with mysql_fetch_object. It segfaults.
Used version: php5-200301240830
configure options:
'./configure' '--with-mysql' '--with-apxs=/usr/local/apache/bin/apxs'
Apache error_log:
[Sun Jan 26 20:29:03 2003] [notice] child pid 729 exit signal
Segmentation fault (11)
Afaik a segfault 11 points to a hardware problem but I only get it when
I use mysql_fetch_object within PHP5.
The function is called within an extended class.
Kind regards,
Hans Wolters
