This code:

iv.it_interval.tv_sec = 0;
iv.it_interval.tv_usec = 250000;

iv.it_value = iv.it_interval;

got miscompiled as:

iv.it_value = iv.it_interval; /* read random */

iv.it_interval.tv_sec = 0;
iv.it_interval.tv_usec = 250000;

That is an obvious compiler bug. None legal optimization can allow the compiler
to do such reordering (not even with strict aliasing enabled).
