That's the COMPONENT_REF case which runs into get_inner_reference which
doesn't deal with invalid MEM_REFs either. It returns t.s as base.

gcc46-pr48134.patch
This fixes it, though perhaps as discussed earlier we want to fold everything
in expand_debug_expr except for memory addresses or something similar.
For 4.6 this is low priority, as with --enable-checking=release it will just
work, so doesn't need to be fixed before 4.6.0 release.
