           Summary: Crash in qualified member call when member function
                    has same name as base class
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: jyasskin at google.com

I'm not sure if this is valid. Neither gcc nor comeau accept it.

dhcp-172-31-155-187:~/tmp$ cat test2.cc
namespace hide {
template<typename T> struct base {
    void bar(double) {}
};
struct Value : base<double> {
    template<typename T> void base(const T& value) {}
};
}
void foo() {
    hide::Value v;
    v.base<double>::bar(3.2);
}
