"Segmentation fault: 11" with @extend?

[jhthorsen]

I'm trying to compile https://github.com/Dogfalo/materialize with CSS::Sass, but I'm getting "Segmentation fault: 11" in OSX 10.11.4, Perl v5.22.0 and CSS::Sass 3.3.0.

The way to reproduce it is:

git clone https://github.com/Dogfalo/materialize.git
cd materialize
perl test.pl

The content of test.pl:

#!/usr/bin/env perl
use strict;
use warnings;
use CSS::Sass ();

CSS::Sass::sass_compile(<<'HERE', include_paths => ['sass']);
@charset "UTF-8";
@import "components/color";
@import "components/variables";
@import "components/cards";
@import "components/buttons";
HERE

I've tried different things, but it seems like I'm able to compile it, if I comment out @extend .btn; in https://github.com/Dogfalo/materialize/blob/master/sass/components/_buttons.scss#L185

Pretty sure this is related to libsass directly and probably a direct duplicate of https://github.com/sass/libsass/issues/1916. Therefore closing this and tracking upstream. If you think this is a different error, feel free to open an issue directly with libsass. If you want to get it solved faster please provide a standalone and reduced test case as we normally do not dig into other people frameworks. Thanks!

Thank you! Yeah, that sounds spot on.

OK, hope we can get a fix out soon, but don't quote me on that ;)
