Summary: [C++11] Rejected valid double expansion packs.

Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

Failing code with double parameter pack expansion.
The attached code fails to compile with pretty much any version of GCC (up to
the head of the Git repository), with -std=c++11, complaining about the double
parameter pack expansion. When using the brace-initialization syntax instead
(commented-out in the attached code), the code compiles fine.
Clang 3.5 compiles both versions fine.
