 Reduced snippet:
 
 ---------------------------
 struct Foo
 {
     template <class>
     void func() {}
 };
 
 template <class>
 void Bar(Foo* p)
 {
     p->func<int>();
 }
 
 int main()
 {
     Foo c;
     Bar<int>(&c);
 }
 ---------------------------
 pr8222.cpp: In function `void Bar(Foo*)':
 pr8222.cpp:10: error: expected primary-expression
 pr8222.cpp:10: error: expected `;'
 
 The obvious workaround is to put the template keyword before func, as in
 "p->template func<int>()". But §14.2p3 [temp.names] specifies that the
 keyword is compulsory only if the postfix-expression is dependent, which is
 not the case in the above snippet. So the above code is legal and should not
 be rejected. This might be a duplicate though, I think I saw a similar
 report somewhere.
 
 Confirmed on every GCC up to mainline 20030430.
