I don't know boost::allocate_shared but if that's working with a standard allocator, then that should work too. Can you attach the errors.

This one compiles fine.

hm, which version of eigen do you have ? I've nothing line 669 of Memory.h; neither in 3.0.5 or 3.1-alpha2.

also your example first compiles fine here with 3.0.5 or 3.1.0-alpha2

It was with 3.0.1/3.0.2.
I just updated Eigen to 3.1.0-alpha2, and it works now. Thank you.
