    * gc.c (stack_end_address): use local variable address instead 

of
__builtin_frame_address(0) to avoid SEGV on SunOS 5.11 on x86
with
gcc (GCC) 3.4.3 (csl-sol210-3_4-20050802).
stack_end_address returned a frame address of garbage_collect
since stack_end_address doesnt create its own frame.
So a VALUE stored in a callee saved register, %edi, pushed
into
the stack at the beginning of garbage_collect was not marked.
