>Description:
compiling the below snippet with 'g++ -c -O2 bla.ii' segfaults.
I did a small trace of the SEGV, and it happens because lookup_anon_field() return NULL for the requested anon field, because somehow it's called (from build_class_member_access_expr()) with both parameter T and TYPE being the same.  I don't know why.  I _guess_ this might
be a duplicate of 8863, but because of missing attachment there I couldn't check.
---------------
struct Bla
{
  void operator()();
};

struct Adjustment {
  void set_lower(float lower) {changed();}
  union {
    Bla changed;
  };
};
