The experimentation I did to develop the test case suggested that the
problem only occurs when the result of a function returning float is
stored directly into a union member. That's a sufficiently weird case
that I'm reasonably confident it doesn't occur elsewhere in the backend.
It might be worth Stefan's time to vary the test case a bit (eg try
double instead of float, struct instead of union, etc) and see just how
general the bug is.
