Internet Explorer (in accordance with the spec) does not accept calculations without spaces for additions/subtractions (ie. calc(100%-30px) is invalid, but calc(100% - 30px) works fine). Refer to CanIUse.com. Most probable reason of your crash is that the Less is removing spaces when escaping the value.
