"That one is turning toggle on, turning toggle off, hitting play, escaping play then turning toggle back on and crash"

Core dump file with debug symbols.

My modified version of SimpleFPSTemplate

EDIT The Toggle Bug does not happen in MarchingCubes with the debug editor.

So to go further I downloaded MarchingCubes and the latest Voxel, I installed voxel in MarchingCubes' Plugins folder and launched the editor on Linux. The editor crashes on launch with this message:

Hi, I have encountered exactly the same problem as @S-Marais . UE4.17.2 @ Ubuntu 16.04

I've also posted on the main UE forum, I guess I should have just posted here. I'm getting a nearly identical crash on Mac OSX 10.13.6, I notice that the crash handler pretty explicitly states to "use ELoadingPhase::PostConfigInit on your module".
