Error with sass files and ampersand

[mlankenau]

Hi there,

I am running into problem with source-map. It is used in brunch that is used in my elixir/phoenix project. The problem is about bootstrap_sass files. It fails with a mapping error when the ampersand syntax is being used. E.g.:

.blockquote-reverse,
blockquote.pull-right {
  padding-right: 15px;
  padding-left: 0;
  border-right: 5px solid $blockquote-border-color;
  border-left: 0;
  text-align: right;

  // Account for citation
  footer,
  small,
  .small {
    &:before { content: ''; }     // <<<<<=========== here I got the error
    &:after {
      content: '\00A0 \2014'; // nbsp, em dash
    }
  }
}

I am not the biggest Javascript dev, otherwise I would try to fix it on my own and provide a PR.

I have encountered the same Problem, though it does work on one of the machines i tested it on.
The problem seems to be a negative column in the original file if an ampersand is used.

I did a really dirty fix by adding a return; before the validation checks in the SourceMapGenerator.prototype._validateMapping function in node_modules/source-map/lib/source-map-generator.js on the machine it did not work on.

I just ran into this as well. Tracked it down to an issue with sass-brunch-2.10.2. Rolling back to sass-brunch-2.10.1 fixed it.

Others are having the same issue. brunch/sass-brunch#141

It appears this may be related to sass/libsass#2312

My understanding from the above is that this is a bug in sass, so I'm closing this report.

I'm not using SASS and I get this error when trying to use webpack obfuscator to obfuscate my javascript project.
