The following invalid code snippet triggers an ICE on mainline:
=====================================================================
template<typename... T> struct A
{
void foo(T*) { ++p; }
T* p;
};
=====================================================================
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc: In member function 'void A<T>::foo(<type error>)':
bug.cc:3: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_unary_op, at cp/typeck.c:4296
Please submit a full bug report, [etc.]
The testcase didn't crash before 2007-11-03, so it's probably fallout from
