Has this problem been fixed?  I see patch from Richard which looks like it
is related:

       * va-ppc.h (__va_start_common): Let __builtin_saveregs do the work.
        * rs6000.c (expand_builtin_saveregs): For V4, initialize a private
        va_list struct, and return a pointer to it.
        (setup_incoming_varargs): V4 save area based off virtual_stack_vars
        instead of frame_pointer.

[ yes, I'm going through my backlog now trying to weed out issues that I
  don't need to deal with :-) ]
