Edit report at http://bugs.php.net/bug.php?id=53292&edit=1 ID: 53292 Updated by: pajoye@php.net Reported by: mmitchell at riccagroup dot com Summary: imap_header crashes when too may To: addresses exist Status: Feedback Type: Bug Package: IMAP related Operating System: Windows PHP Version: 5.2.14 Block user comment: N New Comment: I mean the bug not to get a backtrace. Previous Comments: ------------------------------------------------------------------------ [2010-11-11 18:30:43] pajoye@php.net Try with 5.3.3 please. ------------------------------------------------------------------------ [2010-11-11 18:06:57] mmitchell at riccagroup dot com I tried to do a better back trace this time. I was missing the entry in the debug symbol path this time that downloads the microsoft debug symbols. My Symbol search path is "C:\php;C:\php\ext;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols" For some reason I still get "WARNING - DebugDiag was not able to locate debug symbols for C:\php\ext\php_imap.dll, so the information below may be incomplete." But the .pdb file is at C:\php\ext\php_imap.pdb so I'm not sure why it can't find it. Any ideas? ------------------------------------------------------------------------ [2010-11-11 16:47:31] mmitchell at riccagroup dot com I did a backtrace but it seems to crash in ntdll.dll and I don't know if any of this is useful. I'm not sure how to upload the backtrace file so I will just paste the parts that seem to be important here.

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 for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 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. ------------------------------------------------------------------------ [2010-11-10 23:40:50] mmitchell at riccagroup dot com Description: ------------ Seems that bug http://bugs.php.net/19280 is happening again. When I try to read a mail message with a long list of To: addresses PHP crashes every time. The email I have issues with has a 168 "To:" addresses in it. Test script: --------------- $mbox = imap_open($imapLocation.'INBOX', $user, $pass); $headerInfo = imap_header($mbox, $mailID); // Above will crash if the message being read has too many To: addresses Expected result: ---------------- Should not crash, should parse as many To: addresses as possible Actual result: -------------- PHP exists with a status other then zero. This status changes each time the script crashes. Windows error log shows Faulting application php.exe, version 5.2.13.13, faulting module php_imap.dll, version 5.2.13.13, fault address 0x00046144. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53292&edit=1
