I think g++ incorrectly rejects the following code when compiled with
-std=c++0x:
template <typename> struct X {};
X<decltype(1 > 2)> x;
// t.cpp:2: error: template argument 1 is invalid
// t.cpp:2: error: invalid type in declaration before ; token
For comparison, here is very similar code that is accepted:
template <int> struct Y {};
Y<sizeof(1 > 2)> y;
Hence, I suspect it is a problem with decltype.

------- Comment #1 from reichelt at gcc dot gnu dot org 2008-12-28 23:08 -------
Confirmed.
Btw, the following is accepted:
template <typename> struct X {};
X<decltype((1 > 2))> x;
