The following code (derived from alloc_comp_constructor_1.f90):
! { dg-do run }
! { dg-options "-fdump-tree-original" }
! Test constructors of derived type with allocatable components (PR 20541).

Program test_constructor
implicit none
type :: thytype
integer(4) :: a(2,2)
end type thytype
type :: mytype
integer(4), allocatable :: a(:, :)
type(thytype), allocatable :: q(:)
end type mytype
type (mytype) :: x
type (thytype) :: foo = thytype(reshape ([43, 100, 54, 76], [2,2]))
integer :: y(0:1, -1:0) = reshape ([42, 99, 55, 77], [2,2])
x = mytype(y, [foo, foo])
if (.not.allocated(x%a) .or. .not.allocated(x%q)) call abort()
print *, 'y bounds'
print *, lbound(y)
print *, ubound(y)
print *, 'x%a bounds'
print *, lbound(x%a)
print *, ubound(x%a)
end program test_constructor
compiled with ifort or gfortran, it returns
y bounds
0 -1
1 0
x%a bounds
0 -1
1 0
while compiled with g95, it returns
y bounds
0 -1
1 0
x%a bounds
1 1
2 2
What is the "standard conforming" answer?
