[Bug c++/22454] New: 'template class/operator overloading/default argument' internal compiler error

[gcc at vanviegen dot net]

As describing the problem in words is rather tricky, I'll stick to just 
listing the simplified code and the error message: 
 
---- test.cpp ---- 
template<class X> 
class SortedList 
{ 
    typedef bool (X::*largerThanMethodType)(const X &) const; 
    SortedList(largerThanMethodType cm = &X::operator>); 
} 
 
---- g++ test.cpp ---- 
test.cpp:5: internal compiler error: in cp_lexer_peek_nth_token, at 
cp/parser.c:479 
Please submit a full bug report, 
with preprocessed source if appropriate.

Here's an example with valid code:

=========================================
template<int> struct A
{
    A(void(A::*)() = &A::operator+);
    void operator+ ();
};
=========================================

Btw, apart from the missing semicolon at the end of the class,
the original example was valid, too.

Even shorter testcase:

===============================
template<int> struct A
{
    A(void* = &operator new);
};
