  Target Milestone: ---

Affects versions down to at least r5 :


$ cat z1.f90
integer function n()
   integer :: a(1)
   a = [1] / 0
end
program p
   integer :: b = n()
end


$ cat z3.f90
integer function n()
   implicit none
   integer :: a(1)
   a = [1] / 0
   n = 1
end
program p
   implicit none
   integer :: n
   integer :: b = n()
end


$ cat z5.f90
integer function n()
   implicit none
   integer :: a(1)
   a = [1] / 0
   n = 1
end
program p
   integer, parameter :: b = n()
end
