Your spkg + sage -b to rebuild the extensions blow up in exactly the
same fashion as what is in Sage 3.4.1:

bash-3.2$ ./sage
----------------------------------------------------------------------

------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).
------------------------------------------------------------

The above messages should be clear once you look into
multi_polynomial_libsingular.pyx.

Cheers,

Michael
