(Debian bug #246387)
with text_io;
procedure Test_246387 is
c: aliased constant integer := 3;
type const_ptr is access constant integer;
cp : const_ptr := c'access;
procedure inc(var_ptr: access integer := cp) is
begin
var_ptr.all := var_ptr.all + 1;
end inc;
begin
text_io.put_line(integer'image(cp.all));
inc;
text_io.put_line(integer'image(cp.all));
end Test_246387;
I expect:
test_246387.adb:9:44: incompatible types; expected "access integer", received
"const_ptr"
But I get nothing.
