[Win32] Segfault in "SDL_DYNAPI_entry()"

[GWRon]

I can compile my game ... it executes ... and after a while (during loading of deferred assets - so maybe in threads) I get a segfault. Happens on a Windows 10 machine (not a VM).

Somewhere "outside" of BMX ... so in C.

Starting program: c:\Projekte\TVTower-master\TVTower.debug.exe
