ID: 32971 User updated by: saeven at saeven dot net Reported By: saeven at saeven dot net -Status: Feedback +Status: Open Bug Type: Zend Engine 2 problem Operating System: Fedora Core 2 PHP Version: 5.0.4 New Comment:
Hi, Having compiled with --enable-debug, being forced then to use the unencoded version, the problem no longer occurs. The bug then safely can be assumed to be with Zend Optimizer? Where should I direct a Zend Optimizer bug report? Thanks! Alex Previous Comments: ------------------------------------------------------------------------ [2005-05-07 03:29:56] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. your stack trace is not useful for two reasons: - you need to build a debug build of PHP (which means running without the zend optimizer) - gdb will catch signals like SIGPIPE that are otherwise handled by the program being debugged. You can either tell gdb to "cont" when you see that message, or create a .gdbinit file that has "handle SIGPIPE nostop" in it. ------------------------------------------------------------------------ [2005-05-06 22:16:54] saeven at saeven dot net Description: ------------ Inclusion of a custom user session object at a particular point causes segmentation faults. Occurs in both Zend optimized and un-optimized code. Works on several machines, but fails on a distinct few as well. Apache as well as PHP have been recompiled. Help interpreting the stack trace would be appreciated. Actual result: -------------- Program received signal SIGPIPE, Broken pipe.
