#19325 [Fbk->Opn]: debug apache crashing?

ID: 19325 User updated by: screen@brainkrash.com Reported By: screen@brainkrash.com -Status: Feedback +Status: Open Bug Type: Apache related Operating System: Win2000 PHP Version: 4CVS-2002-09-10 New Comment: Through a long night of compiling i've generated the following debug information. I hope it's helpful. As far as generating code, i'll try and see what I can do. To be honest i'm completely uncertain as to even where to begin. I'll try though... Unhandled exception in Apache.exe (NTDLL.DLL): 0xC0000005: Access Violation.

The happens when requesting the same compontents of specific webpages from the server but does not seem to be directly related to a specific functional group. I've had the crash happen when issuing a simple phpinfo() and it is reaccuring (yet not 100% of the time) for specific code running in a single iframe on a page. Sometimes it is simply an image that is being returned via setting a content-type header and performing a fpassthru. The crash happens when running apache as a service and in console mode. I cannot reproduce the same problems with the same timestamped build compiled for linux. I've tried to find information on how to generate a useful trace log on windows to help get this fixed but I have not found anything in the support lists or on the website. If there is anything I can do to further report this please let me know! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19325&edit=1
