Follow-up Comment #1, bug #36067 (project octave):

This needs more investigation. I found this bug when using a mex file compiled
in octave 3.4.3, which was thus relying on a shared library which no longer
exists. However, I now tried to reproduce this with a simple mex file as
follows:

#include "mex.h"

void mexFunction(int nlhs, mxArray *plhs[],int nrhs, const mxArray *prhs[])
{
  int * p = NULL;
  *p=2; /* assign data to null-pointer, causing seg fault */
    
}

but exist has no problems with this file.

I am recompiling octave 3.4.3 now to see if I can reproduce my original
problem.
