Hmmm, very strange that I get crashes in the 

I am using the SDL android-project as my project structure in 
Android studio. I am replacing the libmain.so which would 
normally be build from c/c++ with a libmain.so file created by D.

Everything compiles, deploys, and seems to work as expected.

Except for random crashes which went away after disabling the GC. 
It might be an interplay between Java, the SDL C trampoline code, 
and D threads or any of the other packages I am using (SDL_Mixer, 
SDL_Net, jni, d_android).

The weirdest thing is that after a segfault, the app closes, but 
swiping up will show the app as still running, clicking on it 
will re-start the app from scratch
