Segfault

[firefart]

After upgrading to sprockets 4 I get the following segfault when trying to recompile the assets. Maybe it's related to #633 ?

The image is built using docker and the latest ruby:alpine image. On another project this runs just without issues so it must be something special here

The manifest.js is just the default one:

//= link_tree ../images
//= link_directory ../javascripts .js
//= link_directory ../stylesheets .css

@schneems I can not provide you a sample app sorry, but it looks like there is a null pointer reference somewhere in the code. Is there perhaps a way to enable debug logging in sprockets to see on which file the error happens?

Hello! Thanks for opening up an issue. In order to move forwards with this issue I'll need an example app that reproduce the behavior (https://www.codetriage.com/example_app).
