Please include a gdb backtrace of the crash into this bug report.
Instructions can be found here:

Also, please include a SHORT script which can (without
any DB's or such) used to reproduce the crash.

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?

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:

  The objects's variables having weird stuff in them is shown in this printout:
