Doesn't work properly with postcss-nested plugin

[dumistoklus]

In example below I got an error after using postcss-csso plugin:

1.scss

.c {
    .touch &:hover {
        color: red;
    }
}

csso.js

const postcss = require('postcss');
const nested = require('postcss-nested');
const csso = require('postcss-csso');
const fs = require('fs');

fs.readFile('1.scss', (err, css) => {
    postcss([
        nested(),
        csso(),
    ])
        .process(css, {from: '1.scss', to: 'result.css'})
        .then(result => {
            fs.writeFile('result.css', result.css, () => true)
        });
});

in result

SyntaxError: Unexpected input

  parseError: { offset: ←[33m7←[39m, line: ←[33m1←[39m, column: ←[33m8←[39m }
}

But without ccso in plugin list, I got correctly compliled file:

result.css

.touch .c:hover {
    color: red;
}
