First of all it would be good to know the sort of troubles
(the best would be some bug demonstration code) that were
the motivation for this commit.

I had a quick look at getfem::mesh_fem class and I think
that the source of problems can lie in the class getfem::context_dependencies.
What I can see there are two vectors of pointers. Please correct me 
if I am wrong but the default (compiler generated) copy constructor and
assignment operator do the bitwise coping what in the presence of pointers
as data membes may cause troubles. 

The question to andrico who commited rev 4120 -- is it possible to 
see the code that produces the troubles you have mentioned ?

Regards

Roman
