--- Comment #1 from Gaius Mulley <gaius at gcc dot gnu.org> ---
Confirmed.

Modula-2 does not allow these kind of constant string to be accessed as arrays.
 However
it obviously shouldn't ICE under any circumstances.

<aside>
For completeness ISO Modula-2 does allow constant strings to be accessed, but
they must be constructed using an array type.  For example:

CONST
   HexDigits = "0123456789ABCDEF" ;

TYPE
   ArrayType = ARRAY [0..HIGH (HexDigits)] OF CHAR ;

CONST
   HexArray = ArrayType { HexDigits } ;

VAR
   ch: CHAR ;
BEGIN
   ch := HexArray[4]
END
