#include <stdio.h>
#include <stdlib.h>
#include "gtk/gtk.h"

void destroy (Widget *w, gpointer g) {

	gtk_exit();
}

int main (int argc, char *argv[]) {

	GtkWidget *win;

	gtk_init(argc, argv);

	win= gtk_window_new(GTK_WINDOW_TOPLEVEL);
	gtk_container_border_width(GTK_CONTAINER(win), 5);
	gtk_signal_connect (GTK_OBJECT(win),
				"destroy",
				GTK_SIGNAL_FUNC(destroy),
				NULL );
	gtk_widget_show(win);
	gtk_main();

	return 0;
}

The above is the simplest program I could write that exhibited
the core dumping when destroy was called by the upper left menu
on the window.

I you add a button, or a menuitem and connect it to the same
callback function it exits normally.

I am using gtk+-971201, with the fvwm window manager. 

I don't think this is a bug in gtk since the same program above
will run properly on a friends box.

For the record, I am using linux-2.0.31 kernel, Xfree svga server vs. 3.1
My hardware is a pentium-120, 32 M memory, 2 G ide quantum drive.
My X settings are straight from the x86config program.

Any further questions, just ask?
