_______________________________________________________
Details:
This is different than a seg. fault. It does not say panic trying to save
etc.
This is probably related to
http://lists.gnu.org/archive/html/octave-maintainers/2017-01/msg00011.html
This only happens with default and control-3.x.x
To see the first example install control pkg. and then run
test h2syn
or
test bstmodred
The crash occures at lin 141 in h2syn.m
It is a call to a .cc file which then calls a fortran subruotine.
[ak, bk, ck, dk, rcond] = __sl_sb10hd__ (a, b, c, d, ncon, nmeas);
The input variables are
a double 6x6
b double 6x5
c double 5x6
d double 5x5
ncon double 1x1 function
nmeas double 1x1 function
It also occures in line 281 of bstmodred. m
[ar, br, cr, dr, nr, hsv, ns] = __sl_ab09hd__ (a, b, c, d, dt, scaled, job,
nr, ordsel, alpha, beta, ...
tol1, tol2);
It also crashes in hinfsyn.m at line 241
[ak, bk, ck, dk, rcond] = __sl_sb10fd__ (a, b, c, d, ncon, nmeas,
gmax);
It also crashes in moen4.m at line 240
[sys, x0, info] = __slicot_identification__ ("moen4", nargout,
varargin{:});
It also crashes in ncfsyn.m at line 383
[AK, BK, CK, DK, RCOND] = __sl_sb10id__ (A, B, C, D, FACTOR);
and at 296
[ak, bk, ck, dk, rcond] = __sl_sb10id__ (a, b, c, d, factor);
And probably more places. I stopped testing, and figured that if we fix these
the rest might be fixed.
Any help would be appreciated.
If you tell me what needs changed I can do the rest.
Doug
