You may want to report that as a GCC bug.

I experienced similar symptoms when reporting PR52748 [1], it could well be the same root cause.

This is not likely to be the same bug. N3276 is about decltype causing the recursive instantiation of a class template -- unconditionally. In this case, a call to the back function succeeds if you pass fewer parameters, but fails with more. Seems to merely indicate an inefficient algorithm, not a fundamental problem. -- Eric Niebler BoostPro Computing http://www.boostpro.com
