Chris,

I had linked to that bit about recode in my original post ( http://www.pingle.org/2006/10/18/php-crashes-extensions ) but you are right, unless it’s really required, it’s probably best to just do away with recode entirely.

Just thought I’d chip in with my findings – php-recode is the culprit in most cases, and has been for almost 10 years.

It’s even documented:

http://www.php.net/manual/en/recode.requirements.php
http://www.php.net/manual/en/recode.installation.php

I’ve been struggling with this since 2002 or so, and every time it is recode that causes problems. Removing recode fixes everything. And – when iconv and mbstring do the same thing (more or less), there’s really no reason to keep recode in the mix.

I had the same problem and tried the re-ordering script on 4 different FreeBSD machines that had the *same* configuration and it worked on some but not on others. Very confusing.

Finally, the solution (for me) was that the extensions could be in any order whatsoever but I had to do a full apache stop + start to stop the segfaults; apache graceful or restart was simply not enough.

WFM; YMMV

Thanks for the great Idea.

With the information on your and Rob’s site I hacked a new script together.

I somehow clobbered my extensions.ini, this helped me out tremendously!

Thanks,

Jim,

Thanks for the script; it didn’t solve my problem, but it pushed me in the right direction.

I documented my steps here, for those who are interested: http://nerdstock.org/php_extensions

Cheers,
Rob

I found that sybase_ct.so needs to be loaded last or else you will also have unknown core dumps. Scripts execute fine but it cores just like everything else mentioned.

Thanks!

again i have now a problem with 5.2.10 version for cli.
i have seen that mssql extension must come after dba extension, otherwise i get “Segmentation fault: 11 (core dumped)” after the script is executed.

Thanks a zillion.
The re-ordering is my problem as well!

I am still trying to solve this problem on one of my servers.

I have tried using the extension reordering script and httpd still core dumps. The work around that I found, although quite unsatisfactory operationally, nevertheless works and it would be useful to find out why.

I found that if I restart the running httpd using apachectl graceful httpd coredumps. However if I comment out the LoadModule php5_module and the AddModule mod_php5.c lines, httpd starts and I can then copy back the uncommented version of httpd.conf and do a graceful restart successfully.

Another graceful restart then crashes httpd.

I am running apache 1.3.41 and php5.2.9 on freebsd 7.0

Any ideas?
