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

[John W. Eaton]

Follow-up Comment #6, bug #60334 (project octave):

I tried the instructions in comment #5.  When I tried to use a build of the
current development version
(--with-mkoctfile=/usr/local/octave/dev/bin/mkoctfile) the mbdyn build failed
with missing symbol errors that I'm not sure I understand.

When I tried again without using the --with-mkoctfile configure option, the
build succeeded (I have Octave 6.2.0 installed from the Debian package) but
running the example does not fail with a segfault:


bash> ./mbdyn -f ../modules/module-octave/demo/octave_element.mbdyn

Although your patch may avoid the crash for you, I'm hesitant to install it
without understanding why the crash is happening.
