The tests are old, they are from 2003 :).
The patch which I was talking about was:
2009-10-30  H.J. Lu  <hongjiu.lu@intel.com>

        PR target/40838
        * cfgexpand.c (expand_stack_alignment): Call update_stack_boundary
        first.  Move assert on stack_alignment_estimated just before
        setting stack_realign_needed.
        (gimple_expand_cfg): Initialize stack_alignment_estimated to 0.
        Don't call update_stack_boundary.

        * config/i386/i386.c (ix86_minimum_incoming_stack_boundary): New.
        (verride_options): Don't check ix86_force_align_arg_pointer here.
        (ix86_function_ok_for_sibcall): Use it.
        (ix86_update_stack_boundary): Likewise.

        * config/i386/i386.h (STACK_REALIGN_DEFAULT): Update comments.
