threaded tracker segfaults on RPI

[danomatika]

Not that this is a main target ... but the threaded tracker segfaults when grabbing positions, features, mesh, etc on the RaspberryPi. It's updating ok, but it crashes when trying to draw (has to grab the position and mesh etc). The example works when I comment out draw() and the variable grabbing.

The non-threaded tracker works but is understandably slow.

I imagine the issue is something to do with synchronization with a slower CPU that we don't see on our laptops. Yeah, thread errors.

i wouldn't be surprised if i've made some kind of mistake with the threaded tracker implementation, but it's really hard for me to debug. i welcome the issue though, and i'll leave it open -- any other info you can provide or alternatives would be super helpful!

Yeah, I can look into it later. It could work but we're going to use a regular PC instead as there is a short time limit. It seemed pretty fast even though I couldn't get any data out of it.
