Comment:
Just to be sure. I've pulled this branch again and recompiled. The same
problem. Here are some of the errors:

At last I've tried to run all single tests via bash (i.e. something like
{{{for i in src/.../root_system/*; do ./sage -t $i; done}}}) and the
results were again fine. This leads me to believe that the problem lies
within SMC. I am notifying William Stein about this problem and setting
positive review on this ticket.
