Harald Anlauf <anlauf at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |anlauf at gmx dot de --- Comment #1 from Harald Anlauf <anlauf at gmx dot de> --- I can reproduce the exception only for -O0, but not for -O1. Note that the exponent is real (1e0), not an integer, and x**y is singular for x=0 and arbitrary y. Did you expect that the result should be well-defined?
