Related to 23634 as it was reduced from that PR (though only to find this bug)

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-01-02 03:08 -------
If we make a tempary variable to hold the array, it works:
subroutine option_stopwatch_s(default_clock)
character(len=2), intent(in) :: default_clock
character(len=2), dimension(1) :: a
a = (/default_clock/)
call option_stopwatch_a(a)
end subroutine option_stopwatch_s
--------------------------------
The problem is obvious in .t02.orginal:
(*(char[0:][1:1] *) atmp.3.data)[NON_LVALUE_EXPR <S.5>] =
*(*(char[0:][1:1] *) atmp.0.data)[NON_LVALUE_EXPR <S.5>];
That is an array copy which is just wrong as there is no such thing in Generic
or the gimplifier can handle.
Confirmed.

the variable does not have to be a "dummy" variable either to reproduce this.
subroutine option_stopwatch_s()
character(len=1) :: default_clock
call option_stopwatch_a((/default_clock/))
end subroutine option_stopwatch_s

Another example of the (probably) same bug (reported by Vivek Rao, reduced by
myself):
$ cat vivek.f90
character(len=1) :: s(1) = ""
integer :: i(1)
print *, s(i)
end
$ gfortran -c vivek.f90
vivek.f90: In function ‘MAIN__’:
vivek.f90:3: internal compiler error: in gimplify_expr, at gimplify.c:5788
The top of the gdb backtrace is:
