Linux  2.4.2 #2 i686 (SuSE 6.4) 
>Description:
A function in class A has overloaded virtual and non-virtual versions.
The virtual version is redefined in public subclass B.
The non-virtual function is not found in subclass C of B.

There is an easy workaround: don't overload function name.

Error message:
no matching function for call to `C::get_a (B &)'
candidates are: int B::get_a()
>How-To-Repeat:

>Fix:
Change name of one of the functions.
