Okay since two day i can make a "correct" version of the daily based PHP5 version. Accept some php-pages with DB-actions and PEAR based are crashing... Apache2 says killed the child etc.

Daily based 4.3x does not have this problem.

Is something changed in PHP5 which ic causing this? I did not change my code...

After setting LogLevel to debug in httpd.conf i found this extra info.

I can now link again (been able since 4 days ago) saw this in my system log. But pages with PEAR are still crashing. I do not have these problems in version 43x.

What is this thing?

It's PHP5. And PEAR is not ready for it.. :)

So i cant use it know? And when is PEAR ready for PHP5...? Keep in mind that it did work?

Does anyone knows where i can find an older (3 weeks ago) PHP5 dev version...

I know get a server hang with the latest build.... today 13:30 GMT

Still with 434 no problem at all

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

Looks fixed in latest CVS.
