//	When the following program is compiled on i386, all
//	three methods of triggering a core dump produce a
//	core file from which gdb can print a stack trace.
//	On PPC, only the third method (assignment via a bad
//	pointer) does so. Anybody know why?
//


#include <unistd.h>
#include <signal.h>

void b(void)				// force core dump
{
	// kill (getpid(), SIGSEGV);	// PPC gdb bt command shows nothing
	// kill (getpid(), SIGABRT);  // PPC gdb bt command shows nothing
	* (int *) -1 = 3;			// PPC gdb bt command shows main -> a -> b
}

void a(void)
{
	b();
}

main()
{
	a();
}
