--- Comment #2 from Erik Carstensen <erik.carstensen at intel dot com> ---
Perhaps the problem is unrelated to function calls; it seems the time is
quadratic in the number of struct literals: If I change argument types to
pointers, then the issue remains if I pass the args as ({static s_t x;
x=(s_t){{0}};&x;}), but it vanishes if I pass them as ({static s_t
x=(s_t){{0}};&x;}).
