 Bug #: 53723
   Summary: [C++11] Variadic template specialisation fails
Classification: Unclassified
   Product: gcc
   Version: 4.7.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sethcarne...@gmail.com


Created attachment 27656
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27656
Example code

The code in the attached file, which should compile, does not. It fails with
the error:

test.cpp:6:5: error: template-id 'foo' for 'int foo()' does not match any
template declaration

I compiled with the following command line:

g++ test.cpp -std=c++11 -Wall -Wextra -fno-strict-aliasing -fwrapv

Also you might want to know that Clang 3.2 accepts the code. There was a
StackOverflow question about it here:

Actually I was using 4.7.1 and I did use g++ -v, I just made a mistake in
simplifying the code from the stackoverflow example. I compiled the
simplification with 4.7.1 but the SO example with 4.7 and assumed it was the
same error (since the error message was exactly the same).
