I think we should be doing the checking against the
typespec of the component.  The component looks reasonable:

p *(rref->u.c.component)
$19 = {name = 0x7ffff5d11fa8 "data", ts = {type = BT_INTEGER, kind = 4, u =
{derived = 0x0, cl = 0x0,
      pad = 0},

but the sym just has

(gdb) p *(rref->u.c.sym)
$20 = {name = 0x7ffff5d11f98 "t1", module = 0x7ffff5d11f88 "m1", declared_at =
{nextc = 0x148a8e0,
    lb = 0x148a8a0}, ts = {type = BT_UNKNOWN, kind = 0, u = {derived = 0x0, cl
= 0x0, pad = 0},
    interface = 0x0, is_c_interop = 0, is_iso_c = 0, f90_type = BT_UNKNOWN,
deferred = 0 '\000'}, attr = {
    allocatable = 0, dimension = 0, codimension = 0, external = 0, intrinsic =
0, optional = 0,
