Display class not properly ported to D2 #111
Description
I think it's not the only one. I tried adding some "mixin(gshared!(...)" etc. But just got a segfault. Shouldn't the docs state that the Linux build is not quite ready?
This test program doesn't reach the second writefln, because Display.getDefault either fails or returns the wrong object:
