The following testcase causes an ICE. It is simply gcc.dg/980502-1.c
invoked with a different set of options, in particular, -fno-tree-dce.
Also included is the output of the final ccp pass. Notice the (dead)
assignment '88 = 1'. It looks like 'line[8]' in an lvalue context was
incorrectly folded to an rvalue. I believe that the RTL phases choke on
this when DCE is not allowed to eliminate it. I produced the output
below using trunk, but the issue shows up in 4.0.3 and probably elsewhere.

------- Comment #1 from rguenth at gcc dot gnu dot org 2008-03-05 15:27 -------
This is done by several passes through the magics of fold_stmt_r:
case ARRAY_REF:
/* If we are not processing expressions found within an
ADDR_EXPR, then we can fold constant array references. */
if (!*inside_addr_expr_p)
t = fold_read_from_constant_string (expr);
else
t = NULL;
break;
we should remember if we are visiting the LHS of an expression here.

Of course the testcase invokes undefined behavior at runtime.

Actually, CCP propagates the invariant address in
D.1547_2 = &"/dev/ptyXX"[8];
*D.1547_2 ={v} 1;
which we cannot undo easily, so we indeed should fold the stmt to a
trap representation.

This happens with the short testcase which does not need -fno-tree-dce and it
only needs -O0:
int main() {
*"c" = 'x';
}
