Remove the template from View and this works.
Janis,
Could you do a regression hunt on this bug?
Thanks,
Andrew

Note that this must be very recent. gcc started rejecting this code between
20060806 and 20060823.

------- Comment #5 from pinskia at gcc dot gnu dot org 2006-09-04 02:32 -------
The problem is here:
/* The array dimension behaves like a non-type template arg,
in that we want to fold it as much as possible. */
max = tsubst_template_arg (omax, args, complain, in_decl);
max = fold_decl_constant_value (max);
It actually does not behave like one if we the decl is inside a function so
that you can use VLAs.
