Gfortran version 4.3.0 20080114 (experimental) [trunk revision 131520]
issues a diagnostic
call b(z(1))
1
Error: Element of assumed-shaped array passed to dummy argument 'x' at (1)
on the attached program. This diagnostic is (a) misleading - b is NOT
an assumed-shape array, and (b) incorrect. I believe the code is
standard conforming Fortran under the provision allowing an array
element to be passed to an array dummy argument.
Gfortran 4.3.0 20071126 (experimental) [trunk revision 130431] compiles
the code without any diagnostic, as do the NAG, g95, ifort, IBM XLF, pathscale,
pgi compilers.
module passtest
integer, dimension(:),allocatable,save :: z
integer, dimension(4) :: t
contains
subroutine a
call b(z(1))
call b(t(1))
end subroutine a
subroutine b(x)
integer, dimension(2) :: x
end subroutine b
end module passtest
