I get what I think is the exact same problem:
mm/slab.c:2243: error: expected an SSA_NAME object
mm/slab.c:2243: error: in statement
# VUSE <SFT.956> { SFT.956 }
D.17707_131 = node_online_map.bits[0];

The source is definitely available, but as it's the same file (although from
another version of the Linux kernel) as that of the original bug reporter it
seems to be of little use.
