            Bug ID: 60299
           Summary: [C++11] Copy constructor calls itself if base class
                    has a constructor which is a variadic function
                    template
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: m.lederhilger@ds-automotion.com

I have made a small example (see attachment) which exhibits the problem.

The generated copy constructor of class C calls itself, and then the base
class's constructor - see disassembly (see attachment of gdb session). This
results in an infinite recursion.
