Description

On Iras:

mabshoff@iras:~/build-3.1.2.alpha2/sage-3.1.2.alpha1-iras-gcc-4.3.1> ./sage -t -long devel/sage/sage/stats/hmm/chmm.pyx
sage -t -long devel/sage/sage/stats/hmm/chmm.pyx            

------------------------------------------------------------
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).
------------------------------------------------------------


A mysterious error (perphaps a memory error?) occurred, which may have crashed doctest.
         [4.4 s]
exit code: 768
 
----------------------------------------------------------------------
The following tests failed:


        sage -t -long devel/sage/sage/stats/hmm/chmm.pyx
Total time for all tests: 4.4 seconds

All other doctests for 3.1.2.alpha1 pass on that box.
