custom_function_override - error_handler

[obriend]

Is it possible to override the error_handler function in custom_functions_inc.php? I added function custom_function_override_error_handler( $p_type, $p_error, $p_file, $p_line, $p_context ) to my custom functions file but the application continues to use the one shipped with the Mantis install.

I would like to add some logic to the function and would prefer to keep do it in my custom configuration.
