"Out of stack space" - karma with IE11 and webpack

[dballance]

Getting the following in IE11 on Windows10 using angular2-webpack-starter and karma-ie-launcher.

IE 11.0.0 (Windows 10 0.0.0) ERROR
  Out of stack space
  at C:/angular2-webpack-starter/spec-bundle.js:1064 <- webpack:///~/core-js/modules/es6.symbol.js:54:0

Offending lines:

 set: function(value){
      if(has(this, HIDDEN) && has(this[HIDDEN], tag))this[HIDDEN][tag] = false;
      setSymbolDesc(this, tag, createDesc(1, value));
 }

Removing / commenting the set descriptor function appears to resolve the issue.

 set: function(value){
      //if(has(this, HIDDEN) && has(this[HIDDEN], tag))this[HIDDEN][tag] = false;
      //setSymbolDesc(this, tag, createDesc(1, value));
 }

PhantomJS and Chrome tests run fine, only IE with this issue. Not sure how to resolve --- it seems to be calling the set method with enough iterations to overflow the stack.

Forgot to add -- possibly related to #96 but unsure how to resolve with webpack + Typescript.

Please, write a simple reproducible example.

@dballance any news about a reproducible example? I don't see the problem just in karma + IE11 + webpack, so looks like this problem in your config.

I haven't had any time to provide a repro for this. It most likely is in my config - will close and provide a repro if it pops up again and I have time to investigate.
