Changing to ice-on-invalid-code. Fixed in 4.8.0 and mainline. I'm adding the
testcase and closing the PR.

Constructing a valid variant was easy.

------- Comment #1 from pinskia at gcc dot gnu dot org 2008-09-07 00:34 -------
This only ICEs on targets where va_list is an array.
Reduced testcase:
typedef __builtin_va_list __gnuc_va_list;
typedef __gnuc_va_list va_list;
template <class> struct S { static const char* foo () { return 0; } };
template <class T, int N>
struct S<T [N]> { static const char* foo () { return foobar (T ()); } };
int main () {
S<va_list>::foo ();
}
--- CUT ---
It does not ICE for powerpc64-linux-gnu but does for spu-elf and
powerpc-linux-gnu.
With 4.1.1, I get the following error message:
t.cc: In static member function static const char* S<T [N]>::foo() [with T =
__va_list_tag, int N = 1]:
t.cc:6: instantiated from here
t.cc:4: error: invalid cast from type int to type __va_list_tag
Also Note I don't think this is valid code.
If we change the template to:
struct S<T [N]> { static const char* foo () { return new T (); } };
I get an ICE even with 4.1.1:
t.cc: In static member function static const char* S<T [N]>::foo() [with T =
__va_list_tag, int N = 1]:
t.cc:6: instantiated from here
t.cc:4: internal compiler error: in build_zero_init, at cp/init.c:260
