EXC_BAD_ACCESS when iterating through verticies in ofMesh

[virusys]

Hi there, lately when I try to iterate through the list of vertices in an ofMesh object, I will get crashes.

Please refer to the attached sample project files:
lua mesh test.zip

Here is the offending block of code in the draw function:

function M.draw()
   M.cam:beginCamera()
   if isPlaying == true then
      local t = timing.beatTickNorm('16b')

      ofSetColor(0, 255, 255, 255)
      --      vbo:draw(GL_LINE_LOOP, 1, vbo:getNumVertices())
      for i=0, mesh:getNumVertices() do
-- crashes here
         local test = mesh:getVertex(i)
      end
      mesh:draw()
   end
   M.cam:endCamera()
end

And the crash log:

pd_2021-12-26-125449_BLOOPITY2.log

Is there a specific way I should be using to look at vertices of ofMesh objects?
