Code: Fixed another segmentation fault

[am11]

With this, the travis-ci build doesn't throw seg-fault. ☺️

There are still two test cases failing on Ubuntu and one on Windows.

@mgreter, can you reproduce these? In Windows this test fails as upstream returns:

  sources:
   [ '..\\included_files.scss',
     '..\\sample.scss',
     '..\\image_path.scss' ],

instead of :

  sources:
   [ '../included_files.scss',
     '../sample.scss',
     '../image_path.scss' ],

In Ubuntu, these two tests fail owing to the fact that upstream puts this comment /*# sourceMappingURL=../out.css.map */ in CSS instead of /*# sourceMappingURL=out.css.map */.

Thanks @am11!

Turned out the Windows issue was due to the post processing of maps in sass.js. #401 fixes it. The Ubuntu issue is fixed in upstream sass/libsass#477.
