--- Comment #7 from Neil Carlson <neil.n.carlson at gmail dot com> ---
Perhaps this modification of comment 2 code is clearer.
Put this in one file:
module mod1
integer :: ncells
end module
module mod2
contains
function get() result(array)
use mod1
real array(ncells)
array = 1.0
end function
end module
And this in another (this is different):
subroutine sub
use mod2
s = sum(get())
end
This gives an ICE when compiled with 8.0.0 (20171222).
NCELLS is a valid specification expression.
A valid full program that calls SUB would have to define NCELLS before doing
so. However it is not required that the compiler know the value of NCELLS at
compile time.
