[Bug 1594422] [NEW] Lambdas with variadic template fail to build

[Pierre Schweitzer]

Public bug reported:

Dear all,

All the G++ shipped with Ubuntu 14.04 (including the latest 4.8 package)
are suffering a bug from G++ in the C++11 implementation. It is not
possible to build code that contains variadic templates with variadic
lambda.

The bug was fixed upstream. Would it be possible to backport the fix?

As an example, you'll find the upstream bug report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41933

It provides examples about how to reproduce the bug. The output of the
compiler is slightly different though, as it is made by G++-4.8.

Cheers
