--- Comment #12 from Sean Anderson <sean.anderson at seco dot com> ---
I ran into this today while debugging U-Boot on aarch64. The real stack is
gdb$ x/8ag $sp
0x1001de10: 0x1001de20 0x10000be4 <fsl_lsch2_early_init_f+12>
0x1001de20: 0x1001de30 0x100013d0 <board_early_init_f+12>
0x1001de30: 0x1001de40 0x10000db0 <board_init_f+32>
0x1001de40: 0x100000f0 <save_boot_params_ret+196> 0x10001124 <_main+36>
So the problem appears to occur with "artificial" frames. Here's what happens
when I try to get a backtrace:
gdb$ set debug frame
gdb$ tar ext :3333
