you need to use

std::pair<const int, Eigen::aligned_allocator<Eigen::Vector4f> > >
Eigen::aligned_allocator<std::pair<const int, Eigen::Vector4f> > >

Note that here, the 3rd parameter "std::less<int>" is just the default value, we only had to specify it because we needed to specify the allocator type, that is the 4th parameter.
Note that the third parameter "std::less<int>" is just the default value, but we have to include it because we want to specify the fourth parameter, which is the allocator type.
