We have also run into this issue. In the editor we crash with a [Position out of bounds!] error. But when we run the code on an iOS device we still get the same error message/stack trace but we don't crash. Instead, meshes simply don't render on the device. We did some digging around and the meshes are empty (no verts). Crossing our fingers for a timely fix as we are trying to move our project to 2017.3.
Reproduced on 2017.3.0f3.

Top prio and completely breaking 2017.3+for us.
Every (Steam) PC game should use asset bundles and mesh compression, so this must affect all PC games?
Please double check how this has passed unit testing since this is really basic.
