[Bug fortran/45045] New: Named COMMON with different size: No warning with -fwhole-file

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Cf. also PR 45044. Long test case: gfortran.dg/common_resize_1.f

Without -fwhole-file or without "call two", gfortran warns:

common /xx/ a, b, c, y
           1
Warning: Named COMMON block 'xx' at (1) shall be of the same size

But as soon as "call two()" is added, no warning is printed. If one uses "call
one()" the warning is printed.


subroutine one()
integer :: a, b
common /xx/ a, b
end
subroutine two()
integer :: a, b, c
real(8) :: y
common /xx/ a, b, c, y
end

call two()
end
