I believe -O0 is the default optimization level, so it is important.

Of course the code I sent you is a fragment from a much larger program,
kind of c**x with c complex and x real. It is not possible to make x
into an integer.

When x is zero and y is real, x**y is singular for y<=0, right?

Also, I do not understand why I get SIGFPE on either zero or invalid
-ffpe-trap suboption,
but this is a lesser issue.
