crashes on exiting octave

[Soeren Sonnenburg-18]

Dear Xavier and list,

I am having weir crashed just when loading swig wrapped octave modules
(using swig 1.3.39 / 40 on both octave3.0 and 3.2).

You can reproduce this by compiling a recent version of shogun (see
http://www.shogun-toolbox.org
./configure --interfaces=libshogun,libshogunui,octave_modular
make
sudo make install

octave

octave:1> init_shogun
-> crash

or slightly closer valgrind+swig1.3.40+octave 3.2.3:

octave:1> Classifier;
octave:2> Regression

I was only able to trigger that problem by loading *two* modules at the
same time. If I just load one then the problem does not occur. Could it
be that there is some kind of overloaded class overlap?

I am quite sure that I don't touch std::basic_string (or even std::
functions) though I am overloading new/delete. However not overloading
new/delete doesn't do anything. Still the same crash.

Any ideas?

Thanks
Soeren
