Dear All
the following junk code is producing an ICE with 4.9.2
v

program min_obj
  implicit none
  integer, parameter :: string_length = 128
  integer, parameter :: max_n_params = 256
  type :: param_t
     integer :: n= 0
     real*8, dimension(256), allocatable :: x
     real*8, dimension(2,256), allocatable :: bounds
     character(string_length), dimension(256), allocatable :: names
  end type param_t
contains
  subroutine extrace_params_from_section ( )
    character(*), dimension(), parameter :: char_params =
['element','parametrization']
  end subroutine extrace_params_from_section
end program min_obj
