nw.js: Crash - Segmentation fault

I’m getting error Segmentation fault: 11 and app crashes. Platform OS X 10.11.5. Using build nwjs-sdk-v0.14.6-osx-x64.zip. Main problem is that i don’t see any logic how this happens. Somehow i think it’s related with window closing ( since it’s the only i use ).

Here’s code i use for close event: nw.Window.get().open('xxx',{width:300,height:300},function(nWin){ nWin.on('close',function(){ nWin.hide(); const foo = nWin.window.foo; nWin.close(true); }); }); Here’s crash dump 7acb46ed-84b5-447a-8ca7-9586e1fb1e8d.dmp.zip
