Watching your original mail, it seems you are not actually using the most recent version:

/usr/local/include/eigen3/Eigen/src/Core/util/Memory.h|729|note: void Eigen::aligned_allocator<T>::construct(Eigen::aligned_allocator<T>::pointer, const T&) [with T = std::__detail::_Hash_node<std::pair<const unsigned int, A>, false>; Eigen::aligned_allocator<T>::pointer = std::__detail::_Hash_node<std::pair<const unsigned int, A>, false>*]|

There is no aligned_allocator::construct() method anymore (we inherit from std::allocator, to get that).

It might be related to this bug:

Where did you get your version of Eigen? Downloaded from our site and
installed, or from some package repository?

The strange thing is, that on the cluster (which uses gcc 4.8.2 as
wellI)  it doesn't compile as well... (os is centos 6)

I cannot remember exactly from which branch I switched. I guess it was
3.2.2 (stable, no dev)

Thanks a lot!

I recently switched to the newest dev version 3.2.90 and
the following compile bug (only under gcc 4.8.2, 4.9 compiles fine )
This code worked before or did I use something incorrectly up to now?

I don't get any errors compiling your code (after adding #include
<unordered_map>) using g++ (Ubuntu 4.8.2-19ubuntu1) and the current
head of the dev-branch.
I guess you either removed something essential from your code snippet
to reproduce this, or you have a buggy c++-library ...

From what Eigen version did you switch (i.e. what date or what
