The same error occurs for the dimension attribute and real variables
gfortran -c test_module.f90
test_module.f90:20:27:
real, dimension(2) :: p
1
Error: Duplicate DIMENSION attribute specified at (1)
module test_module
interface
module function p(a)
real, dimension(2) :: p
real :: a
end function p
module function p2(a)
real :: p2
real :: a
end function p2
end interface
end module test_module
submodule(test_module) test_submodule
contains
module function p(a)
real, dimension(2) :: p ! does not work
real :: a
p = [a,a+1.0]
end function p
module function p2(a)
