            Bug ID: 72791
           Summary: Internal compiler error for reshape intrinsic
           Product: gcc
           Version: 5.4.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: patrick.seewald at gmail dot com
  Target Milestone: ---

I get an internal compiler error (Segmentation fault) when compiling the
following program

program reshape_bug
   integer, dimension(2) :: order1
   integer, dimension(1) :: order2
   real, dimension(2,2,2) :: arr1, arr2

   order1 = [1,2]
   order2 = [3]

   arr2 = reshape(arr1, shape=shape(arr2), order=[order1,order2])
end program

with

$ gfortran reshape_bug.f90

Complete output:
