Confirmed.
sizeof (int [w]));
is causing it.

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-09-26 07:05 -------
Reduced testcase:
template <bool>
static int label (int w)
{
  sizeof(int[w]);
}
int a = label<false>(1);



So I was correct :)

When I get home, I might have a look at this, most likely pt.c needs to be
extended.

------- Comment #6 from pinskia at gcc dot gnu dot org  2006-10-02 07:31 -------
Hmm, the sizeof expression causes use to create the expression:
(cast)NON_LVALUE_EXPR<SAVE_EXPR<(cast)(w)*4>>
