Revision 147978 also does not work if you compile the testcase with
the -fno-tree-sra switch.
New SRA uncovers this problem because it sees the structure containing
only a single field always accessed as a structure and never as a
scalar and so does not scalarize it. Something goes wrong later on,
probably when expanding to RTL. Unfortunately, I cannot help fixing
that.
