Hi, thanks for your work on this gem.

I believe I've found a strange bug that causes a segfault on my machine.

require 'sassc'

scss_string = <<SCSS
  .text-uppercase{
    text-transform: uppercase;
  }

  .initialism {
    font-size: 90%;
    @extend .text-uppercase
  }


  .navbar:has(> a) {
    color: black;
  }
SCSS

SassC::Engine.new(scss_string).render

Which results in a segmentation fault, always.
