    _______________________________________________________

Details:

Essentially running "Anderson.m" demo will core dump octave 4.4.0x
(hg id 194417044d1a). I narrowed it down to both lqr and lqe causing core
dump:



octave:19> L = lqe (G, W, V)
free(): invalid next size (fast)
fatal: caught signal Aborted -- stopping myself...
Aborted (core dumped)
