[Octave-bug-tracker] [bug #60334] Embedded Octave crashes on exit in octave::interpreter::~interpreter()

[anonymous]

Follow-up Comment #7, bug #60334 (project octave):

I see, there seems to be another issue with the development version of Octave
which is related to the number of input arguments.

But maybe you can try also this command:
`./mbdyn -f ../modules/module-octave/demo/octave_const_law.mbdyn`

If I run it, I get this output:

An if I run it through valgrind, I get the same invalid read access:
