hi Kevac Marko
        I had check config_var.mk file .in this file EXTRA_CFLAGS had 
been set -g.
by the way. I think "-g" is only gcc flag for builiding a debug version. 
it has no relation to core file.

Yes, but it allows you to debug your module with gdb (with or without
core file) with ease.

Run gdb bin/httpd, print 'r -X'.
It will start Apache in single mode (with one process).
Than load server somehow and wait for gdb to catch sigfault. It will
show you precise line of code where sigfault occurred.
