--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
static struct builtin_function_entry list_of_builtins[] = {
This is not marked with GTY at all.
Though gm2_isfinite_node is.
static GTY (()) tree gm2_isfinite_node;
So that might not be GC'ed away.
But the return type should not have been `void*`.
It is the gimplification of `__builtin_isfinite (a / b) == 0` which is going
wrong.
