Your ticket #4934 segfault:
http://trac.sagemath.org/sage_trac/ticket/4934
which you were just seeing on cicero is popping up for me on several test
os's on several compilers.
I'm getting exactly this test failure in "make check" on debian 32 and
64-bit vanilla (with gcc-4.1.2) under vmware with 1GB RAM and also the
same failure on 32-bit Ubuntu 1GB RAM (with gcc-4.3.2):
sage -t "devel/sage/sage/matrix/matrix1.pyx"
A mysterious error (perphaps a memory error?) occurred, which may have
crashed doctest.
[4.3 s]
If I do --verbose I get:
Trying:
a._mathematica_init_()###line 171:_sage_ >>> a._mathematica_init_()
Expecting:
'{{Pi, Sin[x]}, {Cos[x], (E) ^ (-1)}}'
ok
------------------------------------------------------------
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).

Under gdb, I get:
