Ugh.  So is the code to create the problem as simple as this?

make
./run-octave
speye (10)

If so, I'm going to have to suggest bisecting.  You know the tip is broken,
I would try going back to 623fc7d08cc6 as the first possible working
revision.  jwe has done a lot in liboctave recently to revamp the
factorization classes and there have necessarily been some changes to
sparse matrices.
