------- Comment #2 from rearnsha at gcc dot gnu dot org  2009-12-23 15:20 -------
Fixed by Paul's patch:

http://gcc.gnu.org/ml/gcc-patches/2009-12/msg00378.html

Prior to this patch, when debugging the testcase I see:

(gdb) 
subfunc (a=492, b=2097148, c=0, d=...) at test.c:9
9               printf("a %x b %x c %x d.y %x d.z %x\n",a,b,c,d.y,d.z);

With the patch, I see:
subfunc (a=0, b=1, c=2, d=...) at test.c:9
9               printf("a %x b %x c %x d.y %x d.z %x\n",a,b,c,d.y,d.z);
(gdb) p d
$1 = {y = 3, z = 4}
