I haven't decided how I want to handle the general case. There are few possibilities: gfortran file.f90 Do nothing, ie., the status quo gfortran -pedantic file.f90 Add a runtime check that x in x**y is not < 0. or gfortran file.f90 Add a runtime check that x in x**y is not < 0. gfortran -ffast-math file.f90 Do not add a runtime check. or gfortran -fsome_new_option file.f90 Add a runtime check. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38823
