>Description:
The following two lines of code cause an ICE
(note that the code is illegal, since B hasn't been defined):

template<typename T> struct A { A(B); };
template<typename T> A<T>::A(B) {}

The error message is:

bug.cpp:1: parse error before `)' token
bug.cpp:2: parse error before `)' token
bug.cpp:2: Internal compiler error in poplevel, at cp/decl.c:1288
