Jekyll throwing Strange Error at library.rb:112

February 7th, 2020

Just had a strange error when renbuilding one of the websites I’m in charge of.. Pretty quickly it turned out, that Jekyll was broken..!? Ruby itself was running as usual, but I couldn’t even ask Jekyll for its version.

The error was very cryptic and didn’t provide any hint on how to fix things. The internet also didn’t help much, that’s why I’m logging it here. I just managed to fix it by chance: A (rather unsimilar) bug report was talking about sassc. As I did not have an idea on how to approach the problem, I just tried (re)installing the tool. And it did the trick…!? Not sure why, and not sure why it wasn’t installed as a dependency with Jekyll, or …!?

However, running

gem install sassc

did fixed it for me (patch for the corresponding Docker image).

Update

The above didn’t actually fully-solve the problem. It just re-installed sassc locally, which fixed the issue in the container on the current platform. However, when I compile the very same image at the Docker Hub and pull the new version it’s broken again..!? The sassc compilation product seems to be plattform dependent!? #wtf

Anyway. I finally got it fixed by installing sassc using --disable-march-tune-native, see also github.com/sass/sassc-ruby/issues/146:

gem install sassc -- --disable-march-tune-native

The updated patch for my Docker image is available from GitHub.

Log

Maybe that can be of help for somebody else? Here is the full error that was thrown:

Thank you!! After over 10 days of a downed website I could almost kiss you on all four cheeks!

That you had this problem 3 years ago is amazing but thank you very much for finding what appears to be a solution. What I continue to not understand is how I encountered this problem. The latest version of my website was built 3 years ago. I have periodically updated my software but never touched the basic support package. I am running ruby on rails with passenger on a digital ocean platform. Nothing was changed on the website (by me) in a 2 hour period when site went to unbootable from working fine. I have restored backups from 4 weeks ago that will no longer boot. How can that be since, supposedly, I am restoring a copy of my whole system?

My bug (identical to what you showed) occours in passenger when it is trying to load my program. I did not dig into your problem but it seems to be under very different circumstances. I am now really questioning the “illegal instruction” error since, it appears, that you found a problem in a totally unrelated routine that supplies file names for the routine that blows up.

I am also mystified as to why hundreds of other people have not reported this problem.

So, while I am very happy that you have restored my website, I actually have more questions now than I did when the problem first occoured. In the unlikely event that I learn something useful, I will update you but, with very polite emails, both passenger and digital ocean said “this is not my problem”

Again, many thanks for chasing this bug down,

David Plummer
