next in thread | raw e-mail | index | archive | help
I installed FreeBSD 6.2-RELEASE, php-5.1.6_3, php5-extensions-1.0,
mysql-5.0.27 and apache_1.3.37_1.
php -i now works Ok after I moved recode.so to the top of the list
of extensions in extensions.ini. It took a while to figure that
one out. Before that php -i would seg fault and core dump. It
took some google searching and using gdb on the core file to fix
it.
A test web page for phpinfo works fine too. Mysql works OK from
the command line.
However I can't get phpMyAdmin to work. It seg faults in reading
/usr/local/www/phpMyAdmin/libraries/url_generating.lib.php
There is no core dump produced.
I ran ktrace httpd -X
Then when I try to open the phpMyAdmin/index.php page in a browser
httpd seg faults.
Here is the tail of kdump from the ktrace.out from the above ktrace.

I moved url_generating.lib.php to url_generating.lib.php.sav and
copied url_generating.lib.php.sav to a new url_generating.lib.php.
Same thing happens.
I tried the latest phpMyAdmin-2.9.2 and it does the exact same thing.
It always seg faults in the exact same place in the exact same way.
/var/log/messages file gets:
Feb 3 16:07:38 testbox kernel: pid 8512 (httpd), uid 80: exited on signal 11
/var/log/httpd-errors gets:
[Sat Feb 3 16:07:39 2007] [notice] child pid 8512 exit signal Segmentation fault (11)
I am out of ideas on what to try next. Anyone else have any suggestions?
TIA,
Terry Todd
