On Ubuntu 16.04 x86_64 Xeon E5-2623 + 16 GB RAM, from a fresh git clone + pull develop, parallel (-j8) build OK and make ptestlong resulted in all tests passed.
However, I've noted some regression, most probably due to the upgrade to Maxima 5.39 introduced in #18920: the hyperbolic plane worksheet <http://nbviewer.jupyter.org/github/sagemanifolds/SageManifolds/blob/master/Worksheets/v1.0/SM_hyperbolic_plane.ipynb> fails at Out[35] with "The kernel appears to have died". A minimal code to reproduce it is sage: H = Manifold(2, 'H') sage: X.<r,ph> = H.chart(r'r:(0,+oo) ph:(0,2*pi):\varphi') # standard polar coord. in the plane sage: Y.<R,ph> = H.chart(r'R:(0,1) ph:(0,2*pi):\varphi') # coord. for the Poincaré disk model sage: X_to_Y = X.transition_map(Y, [r/(1+sqrt(1+r^2)), ph]) sage: X_to_Y.display() R = r/(sqrt(r^2 + 1) + 1) ph = ph sage: X_to_Y.set_inverse(2*R/(1-R^2), ph, verbose=True) ;;; ;;; Detected access to protected memory, also kwown as 'bus or segmentation fault'. ;;; Jumping to the outermost toplevel prompt ;;; Erreur de segmentation (core dumped) Eric. -- You received this message because you are subscribed to the Google Groups "sage-release" group.
