test case

Hello,

I've found the following issue:

Assume you have a class A which has a pure-virtual method called foo which
gets one parameter. Furthermore, assume that A implements a template method
also called foo, which expects 0 arguments and has a template depended return
type.
Class B inherits from A and implements foo with one parameter.

When you call foo without parameter on an instance of B, gcc complains that it
expects a parameter, even if the template type is passed.

This is the error message, an example implementation is attached.

main.cc:33:20: error: expected primary-expression before ‘>’ token
main.cc:33:22: error: expected primary-expression before ‘)’ token
