### 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 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/hmm.pyx sage -t -long devel/sage/sage/stats/hmm/hmm.pyx ------------------------------------------------------------ Unhandled SIGSEGV: A segmentation fault occured in SAGE.

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