--- Comment #1 from janus at gcc dot gnu.org ---
When removing the SAVE attribute ...


module mytypes
   implicit none
 contains
   pure integer function get_i ()
     get_i = 13
   end function
end module

program test
  use mytypes
  implicit none
  integer, dimension(get_i()) :: x
  print *, size (x)
end


... it compiles fine with all tested versions. However, this variant is a
regression of the patch for PR 55207, see:

https://gcc.gnu.org/ml/fortran/2014-03/msg00108.html

However, as comment 0 shows, it is not a problem introduced with that patch,
but it is rather a long-standing problem that is only uncovered by the patch
(according to F08, variables in the main PROGRAM implicitly get the SAVE
attribute).
