// |jit-test| skip-if: !wasmGcEnabled()

// White-box test for bug 1617908.  The significance of this test is that the
// type $S is too large to fit in an inline TypedObject, and the write barrier
// logic must take this into account when storing the (ref $S2) into the last
// field of the object.
