ID: 11218 Updated by: zeev Reported By: [EMAIL PROTECTED] Old-Status: Open Status: Feedback Bug Type: Scripting Engine problem Operating system: PHP Version: 4.0.5 Assigned To: Comments: I was unable to reproduce that problem, however, I did fix bug #10911 which appears to be based on the same issue. Can you please test the latest CVS and see whether it solves your problem (note, this fix may not be a part of 4.0.6, since 4.0.6 has already been packaged; It'll definitely be in 4.0.7) Previous Comments: --------------------------------------------------------------------------- [2001-06-05 17:20:08] [EMAIL PROTECTED] Bug 10911, http://www.php.net/bugs.php?id=10911, was brought to my attention.
