Segmentation fault when re-building about helix HOT 5 OPEN

I think the issue has to deal with the fact that we've loaded the library in memory when we run rake build in the parent project.

Might be able to fix this by not loading the entire application when our rake build happens, but the default Rakefile looks like this:

require_relative 'config/application'

Rails.application.load_tasks

so that might be rather difficult...

You can see that native.so is loaded by printing out $" after the ParentBuildTask#build loop.

Issue is with copy_native. We copy over the native library when it's already loaded.

Ah interesting, we've done a lot of our active testing on macOS which behaves a bit differently in this area. Probably the solution would be to detect the rake build happening and avoid loading the native extension in this case, if that is feasible.

is there a temporary workaround that doesnt involve rebuilding everything? my rust crate is rather large

Confirmed on Ruby 2.2, Rails 3.2 on Debian Jessie.
