[Octave-bug-tracker] [bug #36067] bug in exist() when checking for a faulty mex/oct file

[Kris Thielemans]

Follow-up Comment #2, bug #36067 (project octave):

ok. I can currently not cause a crash, but definitely cause strange
behaviour.

Here's a simple (non-sensical) mex file called existtest.c

#include <mex.h>
void mexFunction(int nlhs, mxArray *plhs[],int nrhs, const mxArray *prhs[])
{
    int dims[3]; /* I didn't bother to fill this in */        
    plhs[0] = mxCreateNumericArray(3,dims,mxSINGLE_CLASS, mxREAL);
}

Now start octave 3.4.3, and type

mex existtest.c

Now start octave 3.6.1. Let's see what happens there:

octave:1> exist('existtest.bla','file')
error: caught execution error in library function


This shows that exist() actually did try to do something with existtest, even
though I'm asking for existtest.bla.

FYI, the error that was caught is a shared library problem caused by compiling
a mex file with 3.4.3, but using it in 3.6.1.

octave:1> existtest
error: /home/kris/windows/Documents/devel/octave/test/existtest.mex: failed to
load: liboctinterp.so.0: cannot open shared object file: No such file or
directory
