This is what I get with GMP 6.1.1 (Sage 7.3.rc0, GCC 5.4.0):

(Haven't tried to change any doctests yet. Again, the failure in
src/sage/matrix/matrix_double_dense.pyx is just the usual numeric noise,
cf. #21119.)
The backtraces for src/sage/structure/sage_object.pyx are horribly long,
but in the stack backtrace there is:
