uncommenting the resize fix the issue on linux.
valgrind reports no error any more.
What was the problem ?

73d81cc55a gf: correct bug in matsubara_freq mesh point
- bool at_end() for a mesh point means AFTER the last point ,
as end in STL. It was not correct ( +1 missing).
- also the at_end was not computed in the mesh product.
- it slightly changes the test_fit_tail --> just changed the output.
--> did this bug affect other functions/codes ?

da7e7ec971 Fixed fit_tail for pos. and neg. matsub + bosonic
-> code was previously assuming mesh with only positive, fermionic matsubara freqs
-> changed wn_min to n_min (was misleading, since it was an index, not a frequency) / same for <-> max
-> changed doc accordingly

9ce291d640 gf: update gf imfreq for g( om - nu) case
DRAFT : to be tested further...

- update gf<imfreq>
- write a specific mesh for matsubara frequencies
- now the cast series is :
  mesh_pt --> matsubara_freq --> complex<double>
- matsubara_freq is just the matsubara frequency
- arithmetic of the mesh_pt casted to matsubara_freq
- arithmetic of matsubara_freq is casted to complex, except + and -,
  which are kept as matsubara_freq.
- evaluator now accept : int, mesh_pt, and matsubara_freq
  for matsubara_freq : for negative omega, use conjugation
  for omega outside windows, evaluate the tail on omega.
- as a result : g( om - nu) where om, nu are 2 meshes points,
  is the extrapolation outside the grid if necessary.
- updated tests
- added evaluation for tail.

6326c2b4eb gf/clef. Bug fix, and added scalar->matrix reinterpret for blocks
- clef : fix a little bug in storage when evaluating
  (was using the wrong trait to deduce storage type).
- gf : block :
     - added reinterpret_scalar_valued_gf_as_matrix_valued
       for block function
     - cleaned make_block_gf_view_from_vector
     - added make_block_gf_view_from_vectormake_block_gf_view_from_vector_of_cython_proxy
       and changed the cython accordingly because it requires a slightly different syntax.
     - updated tests
- gf : cleaned some template.

579368f24b gf. Clean Fourier
- lazy_fourier and co --> fourier
- ex fourier --> make_gf_from_fourier to make a new gf
- = fourier (g) works only iif lhs is a view, like scalar.
- updated python (commented fourier method).

39edb2f846 [API change] gf : factories -> constructors
- Make more general constructors for the gf.
  gf( mesh, target_shape_t)
- remove the old make_gf for the basic gf.
- 2 var non generic gf removed.
- clean evaluator
- add tensor_valued
- add a simple vertex test.
- clean specialisation
- Fix bug introduced in 1906dc3
- forgot to resize the gf in new version of operator =
- Fix make_singularity in gf.hpp

- clean resize in operator =

- update h5 read/write for block gf
  - changed a bit the general trait to save *all* the gf.
  - allows a more general specialization, then a correct for blocks

- NOT FINISHED : need to save the block indice for python.
  How to reread ?
  Currently it read the blocks names and reconstitute the mesh from it.
  Is it sufficient ?

- clean block constructors

 - block constructors simplest possible : an int for the number of blocks
 - rest in free factories.
 - fixed the generic constructor from GfType for the regular type :
   only enable iif GfType is ImmutableGreenFunction

- multivar. fix linear index in C, and h5 format

  - linear index now correctly flatten in C mode
    (was in fortran mode), using a simple reverse of the tuple in the folding.
  - fix the h5 read write of the multivar fonctions
   in order to write an array on dimension # variables + dim_target
   i.e. without flattening the indices of the meshes.
   Easier for later data analysis, e.g. in Python.

- merge matrix/tensor_valued. improve factories

  - matrix_valued now = tensor_valued<2>
    (simplifies generic code for h5).
  - factories_one_var -> factories : this is the generic case ...
    only a few specialization, code is simpler.

- clef expression call with rvalue for *this
- generalize matrix_proxy to tensor and clean

 - clean exception catch in tests

  - exception catching catch in need in test
    because the silly OS X does not print anything, just "exception occurred".
    Very convenient for the developer...
  - BUT, one MUST add return 1, or the make test will *pass* !!
  - --> systematically replace the catch by a macro TRIQS_CATCH_AND_ABORT
    which return a non zero error code.
   - exception : curry_and_fourier which does not work at this stage
   (mesh incompatible).

- gf: clean draft of gf 2 times
  - comment the python interface for the moment.
  - rm useless tests

f0dfabff38 Change tail implementation with fixed array size
Now the tail have a fixed size. It actually makes everything simpler. I took
order_min = -1 and order_max = 8. This makes the tails compatible with the
previous implementation. However we might want to change this to something like
-10, 10 so that they are self-contained. This commit should also fix issue #11.
