[kkojima at gcc dot gnu dot org]

I've got an ICE with gcc.c-torture/compile/951116-1.c test
on sh64-unknown-linux-gnu and powerpc64-unknown-linux-gnu.
On powerpc64-unknown-linux-gnu, with -O -g -m64

951116-1.c: In function 'f':
951116-1.c:9:1: internal compiler error: in mem_loc_descriptor, at

    initialized=VAR_INIT_STATUS_INITIALIZED)
