--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  Doesn't happen w/o -fstrict-enums (huh).

that's the OverflowSafeInt(long) {} CTOR.  We have cgraph_node::get
(t)->definition == 0.

It might be the --param disables some important cgraph initialization
(edges rebuild?).  But not sure where -fstric-enums comes into play.
