Seems that I need debug version of php4ts.dll - I don't know where to get any and failed to compile one myself from recent sources snapshot.

From time to time on some pages Apache crashes. I can't provide a simple script, because framework is rather big and I unable to trace where the error comes from. There are instructions how to get debug info for GDB under *nix on this site, but no instructions how to get it on windows platform. Perhaps I could dig more if such information will be available. For now I've got this from WinDBG and Dr.Watson (second is available at http://rapidshare.de/files/4379016/drwtsn32.log.html) Reproduce code: --------------- Loading Dump File [G:\Documents and Settings\All Users\Documents\DrWatson\user.dmp] User Dump File: Only application data is available Windows 2000 Version 2195 UP Free x86 compatible Product: WinNt System Uptime: not available Process Uptime: not available Symbol search path is: *** Invalid *** : Verify _NT_SYMBOL_PATH setting Executable search path is: .........................................................................
