[Bug fortran/18752] New: ICE from index triplet arithmetic for character variables

[paul dot richard dot thomas at cea dot fr]

I thought that I had already submitted this one - a search through "my bugs" 
and such keywords as I could think of did not succeed in finding it.  If this 
is an old bug, please accept my apologies:

The code below causes an ICEtest_triplet.f90: in gfc_trans_scalar_assign, at 
fortran/trans-expr.c:2005.  It is specific to CHARACTER variables and, of 
course, element by element assignment within a DO loop works fine.

program test_triplet
   Character(len=5), dimension(4 )   ::  i 
   integer                 ::  idx = 1 , N = 4
   i  = (/"one  ","two  ","three","four "/)
   i( N : idx + 1 : -1 ) = i( N -1  : idx  : -1 ) 
   print * , i
end program test_triplet

Compilation of the following piece of code gives the same error message:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
program test
  character, dimension(2) :: a
  integer :: i=1,j=2
  a(i:j) = a(i:j)       ! gives internal error
! a(1:2) = a(1:2)       ! works fine
end program test
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
