with amd64:
$ clang -O3 -g -o test plop.c
$ gdb test
GNU gdb (GDB) 7.4.1-debian
[...]
Reading symbols from /tmp/test...done.
(gdb) b main
Breakpoint 1 at 0x400524: file plop.c, line 5.
(gdb) run
Starting program: /tmp/test

Breakpoint 1, main () at plop.c:5
5        printf("%-6d%-6d\n", i, i*i);
(gdb) bt
#0  main () at plop.c:5
