(Potential problematic code below):\n\n```\nassertionsEnabled_ = typeof _global['assert'] !== 'undefined';\n_global.assert = function assert(condition) {\n  if (assertionsEnabled_) {\n    _global['assert'].call(condition);\n  }\n};\n```\n\nThis code seems fine for the first definition (as `assertionsEnabled_` resolves to false), however, the second time around it resolves to true, therefore, whenever `window.assert` is called, Angular seems to get itself caught in an infinite loop, exceeding the maximum stack size.\n","author":{"url":"https://github.com/nweedon","@type":"Person","name":"nweedon"},"datePublished":"2015-08-28T18:41:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/3890/angular/issues/3890"}
