--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> 2013-02-14 21:08:19 UTC ---
Trunk gives an error not an ICE:

t.cc:5:8: error: partial specialization is not more specialized than the
primary template because it replaces multiple parameters with a pack expansion
 struct MyClass<args...> {};
        ^
t.cc:2:8: note: primary template here
 struct MyClass;
        ^

I think this is a dup of PR 52008

*** This bug has been marked as a duplicate of bug 52008 ***
