Bug Report

[xiaoxiaosl]

The libsass have a bug that for example

.test {
 content:'test';
 @at-root . #{&}_c{
      content::' test_c'
   }
}

Libsass

.test{ content: 'test'}
.test .test_c{ content: 'test_c'}

Ruby Sass

.test{ content: 'test'}
.test_c{ content: 'test_c'}

@Prince-Raul the code you have supplied is not valid Sass. It does not compile with Ruby Sass.

I assume you meant the following

.test {
  content: 'test';

  @at-root #{&}_c {
    content: 'test_c'
  }
}

In which case this is a duplicate or #1210 and has been fixed. It will be in the next version of LibSass.
