ICE example

Hi,

In programs like the example below:



program example

   type :: Parent
      integer :: member1 = 0
   end type Parent

   type, extends(Parent) :: Child
      integer :: member2 = 0
   end type Child

   integer, parameter :: member1 = 23
   integer, parameter :: member2 = 42

   type(Child), parameter :: object = Child(member1, member2)

   print *, object%member1  !<-- No ICE if commented out
   print *, object%member2

end program example



I get the following message (on versions 4.6.4 and 4.7.3):



f951: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions.



Best regards,
