Segmentation fault with specific @media and @at-root combinations

[anlutro]

I'm using sassc (compiled from master today) and ran across a segmentation fault with a specific combination of @media, selectors and @at-root.

This is the minimal code I've been able to reproduce the segmentation fault in.

@media screen
    .two
        @at-root .one
            background: blue
            .three
                color: red

$ sassc ./test.sass 
Segmentation fault

Removing any bit of this example makes it compile just fine - it's something about the combination of rules (background: blue) and selectors (.three) within the @at-root declaration that's messing up.

I've confirmed this is an issue on the latest master

@media screen {
  .two {
    @at-root .one {
      background: blue;
      .three {
        color: red;
      }
    }
  }
}

@xzyfer Does this mean I missed a case with my @at-root test suite?

It would appear so.

I've got a fix #861.

I don't have time to create the spec now, but when I do this is ready to go.

Spec added sass/sass-spec#248

This is fixed and will be 3.2.

Awesome. I love using sassc, keep up the great work :)
