g++ is unable to compile a call to a templatized method from a template
function that takes the class that contains the templatized methods as
a template parameter.

How-To-Repeat:
1) save the following code into bug.cpp
struct foo {
template <int n>
const void* bar(char* p) const
{
return p;
}
template <typename T>
const void* moo(char* p) const
{
return p;
}
};
template <typename F>
void test_template(const F& f)
{
f.bar<3>(0); // doesn't work here
f.moo<int>(0); // doesn't work here
}
int main(int argc, char* argv[])
{
foo f;
f.bar<3>(0); // works here
f.moo<int>(0); // works here
test_template(f);
return 0;
}
2) attempt to compile: g++ -o bug bug.cpp
