Really? Easy to test. Remove the line with 'objects.ground.shape:getPoints()'. Alternatively, try this 0.9.0 build which has a fix in it. love.physics didn't change (all that much) so the code should work there too.

Edit: With regard to the deleted post.

Note that there are three different getPoints. PolygonShape, EdgeShape and ChainShape all have their own function for this. They all return numbers and, because of implementation specifics, these values do not have to be collected by the gc.

The default love.run creates some garbage. I think this is because it generates the C closures with love.event.poll. You're forcing it to collect with collectgarbage("collect") anyway.

If there is another issue, any information would be welcome of course.

You're absolutely right boolsheet. In fact, draw calls were being completed before the program crashed, even with my extra call to collectgarbage.
