Normally that difference isn't a problem because canonicalizing template arguments strips non-dependent aliases, but that wasn't happening for the pack expansion. Fixed thus. gcc/cp/ChangeLog: PR c++/99445 * tree.c (strip_typedefs): Handle TYPE_PACK_EXPANSION. gcc/testsuite/ChangeLog: PR c++/99445 * g++.dg/cpp0x/alias-decl-variadic1.C: New test.

So the template args hash differently but compare equal.

I'll see when I can repeat it. I can imagine. Or you can try to somehow "fix" the reduced test-case so that it's valid again :)
