ID: 48744 Comment by: dougcsd at yahoo dot com Reported By: tom at ideaweb dot de Status: Feedback Bug Type: Safe Mode/open_basedir Operating System: Linux Debian Etch PHP Version: 5.3.0 Assigned To: fb-req-jani New Comment:
Here is more info on this. I ran into this earlier while running 5.3 Alpha snapshots. The Snapshot: php5.3-200810090430 (Alpha 3) did not seem to have this problem yet, and works ok. I have reproduced the problem on two machines and multiple operating systems. I see the scrambled open basedir paths in the apache logs when a simple phpinfo() fails. Both systems were running Slackware 12.1 (one 32 bit, and one 64 bit) BlueWhite64 for the 12.1 64 bit. I recently upgraded to Slackware 12.2 on the 32 bit machine to upgrade the libc to a newer version and see if it helped, but the problem persists. I first saw this problem in php5.3-200903230730, and assumed it was a development bug that would work itself out in time, and simply reverted back. However the problem has carried over to 5.3.0 release. I have done a bit of digging and it appears that both PHP and Apache are using pthreads on these machines. Because of the randomness of when the corruption occurs, I believe this may be related to a threading issue, but I have yet to discover any additional details.

That's propably the only way to debug this. Otherwise, just let this rot. ------------------------------------------------------------------------ [2009-07-15 07:29:24] tom at ideaweb dot de Sorry for the delay, the test server was in use...
