--- Comment #2 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- $ cat bug1.f90 program vincenty implicit none real, parameter :: f = .2345 real :: tmp tmp = 1.0 − f end program $ gfc49 bug1.f90 bug1.f90:7: tmp = 1.0 \xE2\x88\x92 f 1 Error: Unclassifiable statement at (1) Notice that gfortran 4.9 displays the hidden characters. I have trash in the file. gfortran later versions do not display it, so one gets very confused. I consider this a diagnostic regression tat should be fixed. So with versio 8, a mysterious error. $ gfc bug1.f90 bug1.f90:7:0: tmp = 1.0 − f Error: Unclassifiable statement at (1)
