Compiling with this command: gcc -o memtest memtest.c -ggdb3 3. run the program using gdb Actual Results: (gdb) s init () at x.c:7 7 ptr = malloc (2); (gdb) where #0 init () at x.c:7 #1 0x0804845e in main (argc=1, argv=0xbffff694) at x.c:15 (gdb) s 8 } (gdb) where #0 init () at x.c:8 #1 0x0804845e in main (argc=0, argv=0x20ff1) at x.c:15 (gdb) s main (argc=0, argv=0x20ff1) at x.c:16 16 return 0; (gdb) where #0 main (argc=0, argv=0x20ff1) at x.c:16 (gdb) q The program is running.
