The only way I've managed to create breakpoints at multiple locations is
by specifying a line number inside the template/constructor.  For templates
I understand that the breakpoints are for different types, e.g., float, int
as used by the program.  For constructors:


   * For a C++ constructor, the GCC compiler generates several
     instances of the function body, used in different cases.

I don't understand what the second breakpoint refers to, or why there may
be more than one instance.

So I think, at some point, a separate node, or one grouped with breakpoint
menus to highlight the differences, would be a good idea.  Other things, like
needing to include the return type in the template name when specifying a
breakpoint location could also be included.
