The following invalid code snippet triggers an ICE on mainline:
==================================================================
template<typename...> struct A;
template<typename...T, typename...U> struct A<A<T...,U...> > {};
A<A<int,int> > b;
==================================================================
bug.cc:5: internal compiler error: in unify, at cp/pt.c:13178
Please submit a full bug report, [etc.]
The testcase was derived from Chris Fairles' testcase from comment #1
in PR 32128.

Mark, this is really only an error recovery regression. Can you relook at the
current priority?
Thanks,
Andrew Pinski

------- Comment #3 from reichelt at gcc dot gnu dot org 2007-12-07 21:43 -------
Both the reduced testcase here and the original testcase in PR 32128 are now
fixed in mainline (probably by the patch for PR 33091).
