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.
