This is enough to see the glibc errors, and, unless I'm badly mistaken, *very*
little changed in std::function between 4.6 and 4.7, thus I doubt it's a
library issue:

#include <functional>

template <typename F>
std::function<void()> animate(F f) { return [=]{ f(); }; }

int main()
{
  std::function<void()> linear1 = []{};
  std::function<void()> av(animate(linear1));
  av();
}
