You are refering to _redupif?

This is a `static` function that is used exactly once. Perhaps the
compiler "augments" it to `float complex` return type, because the
context where it is used is of that type. It would be interesting to
see if the error disappears if the return value is first stored in a
`volatile float`, and only then assigned to `w`.
