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
