3984,Sage 3.1.2.alpha1 - Linux Itanium - segfaults in chmm.pyx and hmm.pyx,mabshoff,mabshoff,"Note: most of the valgrind fix issues have been moved to #4067. Those fixes do not prevent the segfault, so I broke them out.

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

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