I will give the situation a more detailed look later (but yes, I believe this

The problem here is that build_ref_for_offset_1() cannot find a field
corresponding to a replacement within its own aggregate. The field is
identified by its offset (zero) and type. Unfortunately,

As I said the testcase has two incompatible variants of union tree_node and
they are obviously not merged and thus not compatible. Maybe IPA SRA gets
those two types from unrelated places?

Using c-parser.i and c-typeck.i generated from my current trunk tree passes
gcc ./xgcc -B. -r -nostdlib xc-parser.i xc-typeck.i -O2 -flto
just fine. Raphael, was this by chance an ICE you saw during reduction of

typedef struct VEC_constructor_elt_gc {
VEC_constructor_elt_base base;
} VEC_constructor_elt_gc;
vs.
typedef struct VEC_constructor_elt_gc {
} VEC_constructor_elt_gc;
