            Bug ID: 63494
           Summary: internal compiler error: Bus error, and out of memory
                    allocating ...
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jwmwalrus at gmail dot com

With the code below I get two errors while compiling. One with the
preprocessor, and one without.

module my_lrstring
    implicit none
    private
    save

    type :: lrStringType
        character(:), allocatable :: left
        character(:), allocatable :: right
    end type

    type, public :: lrString
        type(lrStringType), allocatable, private :: storage(:)
    contains
        procedure :: getRight
    end type

contains
    pure function getRight(this, left) result(right)
        character(:), allocatable :: right
        class(lrString), intent(IN) :: this
        character(*), intent(IN) :: left
        integer :: i, j
        character(:), allocatable :: text

        right = ''
        j = INDEX(this%storage(i)%right, '{}')
        text = this%storage(i)%right(j+2:)
    end function
end module my_lrstring



The output I get is:

$ gfortran-5.0 -c -g -x f95-cpp-input -Dmy_lrstring=my_lrstring_dbg
my_lrstring.f90
f951: internal compiler error: Bus error
Please submit a full bug report,
with preprocessed source if appropriate.
