Forced replacement prototype accessors methods fails Android 4.0

[ikhilko]

We are using babel-polyfill in our code, and it loads core-js as dependency.
Unfortunately core-js fails application for Android 4.0. After some investigation i found the problem place, but have no idea why problem occurred here:

// Forced replacement prototype accessors methods
module.exports = require('./_library')|| !require('./_fails')(function(){
  var K = Math.random();
  // In FF throws only define methods
  __defineSetter__.call(null, K, function(){ /* empty */});
  delete require('./_global')[K];
});

Browser's engine raised "Uncaught illegal access" exception that for some magic reasons doesn't catched by try/catch while execution line:

__defineSetter__.call(null, K, function(){ /* empty */});

I have tried to replace this line with:

var obj = {};
__defineSetter__.call(obj, K, function(){ /* empty */});
delete obj[K];

and this fixed the problem, but i'm not sure that this is a right solution. So can anyone help me to solve this problem?

Same issue in ios 10.3 iphone7 simulator

__defineSetter__.call(null, "test", function () { /* empty */ });

TypeError: null is not an object (evaluating '__defineSetter__.call(null, "test", function () { /* empty */ })')
