AFAICT all the tests in this PR compile now without any problem. May I close it
as FIXED?

Thanks for the patch. 

Another similar case, this time the type contains an allocatable field,
produces a internal compiler error (without applying the patch) :

 internal compiler error: in fold_convert_loc, at fold-const.c:2112


program toto
implicit none

type mother
integer :: i
double precision,dimension(:),allocatable :: values
end type mother


class(mother),allocatable :: cm,cm2

allocate(cm)
allocate(cm%values(10))
cm%i=3
cm%values=80d0
allocate(cm2)
select type(cm2)
type is (mother)
cm2=cm
end select
print *,cm2%i,cm2%values
end program

Confirmed on 4.9.1 up to trunk (5.0). 4.8.3 gives the error

As I wrote here https://gcc.gnu.org/ml/fortran/2014-10/msg00079.html, 

I think this case is also related : 


program toto
implicit none

type mother
integer :: i
end type mother
type,extends(mother) :: child
end type child

type(mother) :: tm
type(child) :: tc
class(mother),allocatable :: cm,cm2
class(child),allocatable :: cc

 allocate(cm)
 allocate(child::cm2)
 cm%i=10
 select type (cm2)
 type is (child)
cm2%mother=cm
 end select
 print *,'class cm2 is type tm',extends_type_of(cm2,tm)
 print *,'class cm2 is class cm',extends_type_of(cm2,cm)
 print *,'class cm2 is type tc',extends_type_of(cm2,tc)
 print *,'class cm2 is class cc',extends_type_of(cm2,cc)
 print *,'cm2=cm', cm%i,cm2%i

end program

Created attachment 33742
  -- https://gcc.gnu.org/bugzilla/attachment.cgi?id=33742action=edit
patch

This fixes both testcases but causes a few trivial regressions:
class_array_15.f03
data_constraints_4.f90
data_constraints_6.f90

The fix is applied in the wrong place and the above regressions are easily
fixed.

It will be done tonight!
