Having poked at -fdump-tree-all-raw I now think `= {.arityD.2402=0};` is not a
variable initialization itself, but a reference to `DECL_INITIAL` that would do
an initialization.
Perhaps something was supposed to expand this `DECL_INITIAL` to an actual
initializing statement, but did not for this case.
