One side-note:
When submitting test case, make it stand-alone. Please do not include header
files which may not
be available to every one or pre-processed version of such files which may be
under license.

I think here is the test case exhibiting the issue. In the test case, property
reference is not an l-value.
Something the older versions of clang (as well as gcc) were not considering.
Older versions of
clang (but not gcc) would issue the error when message expression version is
used (statement 2).

struct S {
    int x;
};

@interface I
@property struct S rec;
@end

void FUNC(I* foo) {
  foo.rec.x = 10;       // 1
  [foo rec].x = 10;    //  2
}
