Instructions can be found here: http://bugs.php.net/bugs-generating-backtrace.php Also, please include a SHORT script which can (without any DB's or such) used to reproduce the crash. --Jani Previous Comments: --------------------------------------------------------------------------- [2001-01-08 14:01:29] [EMAIL PROTECTED] Could you produce minimal PHP code that reproduces the problem? 1000 lines of DB-dependant application is pretty hard to investigate. Also, do you have some non-standard PHP modules in your application? --------------------------------------------------------------------------- [2000-12-26 13:52:18] [EMAIL PROTECTED] Under Linux, memory appears to be corrupted after Alarm object newed/ or call to DisplayObject function. This is part of a large/complex script, around 1000 lines. Using BODY debugger, variables having weird stuff in them. It is like the memory manager gets hosed. I would be willing to give entire script/database configuration set to anyone. The application is GPL'd. I've got a sample database for MySQL that configures and loads as follows: mysql <mom1create.sql mysql <testdb.sql the crash occurs with either of the following: (command Line) php mom.c crash looks like this: 888888888888888888888888888888888888888888888888888888888888 +++++++++++++++++++<BR>walking TestActionArray<BR>+++++++++++++++++++<BR> <BR><B>Function==CheckTestActionResult(0,0) file /home/httpd/html/mom/momact.c line 203</B><BR> Key 0 not used<BR> <BR><B>Function==CheckTestActionResult(Object,2) file /home/httpd/html/mom/momact.c line 203</B><BR> key 2 for object Object <BR>-----------------------<BR> For Object 'ActionResult ($ARValue)':<BR> -----------------------<BR> new action result!<BR> Creating New Alarm Info Object<BR> $Alarm was NOT set<BR> -----------------------<BR> For Object 'ActionResult':<BR> -----------------------<BR> FATAL: erealloc(): Unable to allocate 1699901065 bytes 888888888888888888888888888888888888888888888888888888 (browser) http://127.0.0.1/mom/mom.php System is running 128 meg on linux.
