I have recompiled Octave 4.2.1 and Dynare 4.5 on Debian Jessie (working around the bytecode issue), in order to mimic the environment of jessie, and I still don't get the crash. I don't understand how I got it in the first place.

It does not look like a problem with consistently uninitialized memory space, because a check with valgrind could not unveil anything.

So I'm giving up on this issue for now.

Thus, the crash happens during or immediately after computing the Hessian.
My hunch is that the Hessian again returns something complex with a NaN in
it and we get the same crash as in the other mod-file when the inverse
Hessian is supposed to be computed.

Well, I am no longer able to reproduce the crash in
kalman_filter_smoother/compare_results_simulation/fs2000_ML.mod.

Do you have a way to consistently trigger it?

Have you tried on Linux whether the problem also occurs on the Linux 
GUI? On the Windows CLI, everything runs smoothly, but there are still 
figures showing up on screen, which is different from the Linux CLI.

Thanks a lot. I cannot replicate the third crash on Windows. On Linux, 
I get

The first one seems to be a bug in Octave. I filed a bug report at ht
tps://savannah.gnu.org/bugs/index.php?51198
 

Thanks. I have added some technical information and a tentative patch 
to the bug tracker.

 

So I think we're done with the crash in 
estimation/fs2000_calibrated_covariance.mod.

 

Let's now investigate the crash in
kalman_filter_smoother/compare_results_simulation/fs2000_ML.mod.

Dear all,

I do not receive integration tests reports for Octave since ages... I 
don't know why. Before the disappearance of the reports we had some 
failing tests, it would be nice to fix them. The difficulty with the 
Octave testsuite is that it often never ends. Some mod files, not 
always the same, run forever. I am convinced that this is not a bug in 
these files but rather a consequence of the memory leaks Ferhat has to 
fix in bytecode.
 
I have run the testsuite for Octave. The environment is Debian 
unstable, with Octave 4.2.1 from Debian experimental, and a few Octave 
forge packages recompiled by hand. The commit tested is
d608588ef2 on the 4.5 branch.

 

Basically there are only 3 test failures :

estimation/fs2000_calibrated_covariance.mod
estimation/fs2000_model_comparison.mod
kalman_filter_smoother/compare_results_simulation/fs2000_ML.mod
 

The first and the third ones are crashes in Octave. I am going to 
investigate them. The second failure is simply the consequence of the 
first failure (the second test needs the output of the first one).
