FWIW, attached are some excerpts from the log, with also some "funny"
errors I at least never noticed before.
As you may already have seen, the crash starts somewhere in
sage/rings/number_field/totallyreal.so, goes through some
Singular-related extension modules up to sage/libs/singular/singular.so,
and "ends" in local/lib/libsingular.so.
Compiler is Ubuntu's "native" GCC 4.8.4-2ubuntu1~14.04.3
(--with-arch-32=i686 --with-tune=generic target=i686-linux-gnu), not
Sage's 4.9.3.
Build is in some VM on a 64-bit machine (Linux sagebu14_32s02
4.5.0-0.bpo.2-amd64 #1 SMP Debian 4.5.4-1~bpo8+1 (2016-05-13) i686 i686
i686 GNU/Linux).
