nested imports of sass files crash node

If I import sass files nested more than one deep and try to build with the webpack sass-loader, node crashes. This occurs even if the second imported file is blank. node(7650,0x106907000) malloc: error for object 0x101b11a6c: pointer being freed was not allocated set a breakpoint in malloc_error_break to debug Abort trap: 6

source: proj/app/sass/_any.scss

<blank>

proj/app/sass/_theme-default.scss - note here if you comment out the @import 'any' line, the crash goes away. You can also crash it by commenting out the import, but then referencing a variable that doesn't exist - i.e. change 'background: white;' to 'background: $bad;'

@import 'any'
.theme-default-header {
    background: white;
    color: black;
}

proj/app/sass/main.scss

 @import 'theme-default'

proj/app/components/Header.jsx

    import React from 'react'
    import '../../sass/main.scss'

    export default class Header extends React.Component {
         render() {
            return (
                <div className='theme-default-header'>
                    'This is the header.'
                </div>
            )
        }
    }

project config using # react-boilerplate - Boilerplate for "SurviveJS - React" webpack config part:

    exports.setupScss = function(paths) {
        return {
            module: {
                loaders: [{
                    test: /\.scss$/,
                    loaders: ['style', 'css', 'sass'],
                    include: paths
                }]
            }
        };
    }
