mini_racer 0.12.0 Segmentation fault on x86_64-linux with libv8-node 21.7.2.0

[D-system]

Hello the team

Thank you for the update to libv8-node 21.7.2.0 yesterday.
I wanted to report an error.
Setup:

• mini_racer 0.12.0
• libv8-node 21.7.2.0
• ruby 3.2.3
• OS: Ubuntu 22.04.3 LTS (from CircleCI cimg/ruby:3.2.3-node)
• Rails: 6.1.7.7
• Sprockets: 4.2.1
• The command: RAILS_ENV=production SECRET_KEY_BASE=1 bin/rails assets:clobber assets:precompile

Received "aborted" signal

It does work on Darwin Kernel Version 23.2.0 arm64 (Mac on arm) that compile from source.

The error is from eval -> eval_unsafe, so I suspect it is an issue with the libv8-node

mini_racer/lib/mini_racer.rb

Line 228 in 5b2a25c

eval_unsafe(str, filename)

Hey @D-system. A couple of question hopefully helping to narrow the issue down

• Can you reproduce it with a freshly created rails application? On aarch64-linux my basic checks works, as well as rails new foo && cd foo && bundle install && RAILS_ENV=production SECRET_KEY_BASE=1 bin/rails assets:clobber assets:precompile using cimg/ruby:3.2.3-node.

• Can you reproduce the issue with Ruby 3.3.0?

• Can you confirm if you're using jemalloc or not? Looks like the image is at least installing libjemalloc, I haven't checked if they build Ruby against it, or using LD_PRELOAD, or using this up to the user. There have been various issues with jemalloc and mini_racer/v8. In case jemalloc is used, can you try without?

[D-system]

I don't think jemalloc is enabled:

$ ruby -r rbconfig -e "puts RbConfig::CONFIG['MAINLIBS']"
-lz -lrt -lrt -ldl -lcrypt -lm -lpthread

Even by using the LD_PRELOAD, it does not seems to work:

$ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2  ruby -r rbconfig -e "puts RbConfig::CONFIG['MAINLIBS']"
-lz -lrt -lrt -ldl -lcrypt -lm -lpthread


# Checking the directory
$ ls -l /usr/lib/x86_64-linux-gnu/libjemalloc*

Let me see if I can make a new app and get the same error.

I didn't realized there was a more debug output:

I made a brand new Rails 6.1.7.7 app I got the same error with those changes:

• remove webpacker
• add gem "bootstrap", "~> 4.3"
• add gem "sprockets-rails" (it does error out with sprockets and without webpacker)
• add gem "mini_racer", "~> 0.12.0"

Note: it does precompile the files then seg fault.

I also tried the same project with mini_racer 0.9. It works.

It seems sprocket is used by default if no other assets pipeline exists.

@lloeki this looks urgent , should we roll out a release that puts us back at an earlier version while we work this out ?

[SamSaffron]

@D-system does this repro in Linux as well

[D-system]

@SamSaffron it's all tested inside the CircleCI image linked above. So, it's an Ubuntu based linux on x86_64.

[lloeki]

should we roll out a release that puts us back at an earlier version while we work this out ?

So the idea would be to have 0.12.1 be 0.9.0? That would be odd.

[lloeki]

I'll try a repro.

The official ruby:3.2.3 Docker image does not have that problem.
Trying with cimg/ruby:3.2.3-node on my local machine (instead of their data centers)

[tisba]

I'm not able to reproduce yet, can't spend much time on it right now though.

The product I'm working on in my day job is using docker images based on the ruby:3.3.0 and we have an extensive test suite with lots of JavaScript that is evaluated by mini_racer. It works with 0.12.0 on x86 and aarch64 (both linux) just fine, I also have no issues on macOS 14.4.1 (arm). Running directly on x86 without Docker in Github Actions is also fine.

🤔

[D-system]

I tried with cimg/ruby:3.2.3-node as base image with --platform=x86_64, I was not able to reproduce the problem.
eg: FROM --platform=x86_64 cimg/ruby:3.2.3-node

I'm not able to reproduce the issue in a local docker either.

[lloeki]

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2 ruby -r rbconfig -e "puts RbConfig::CONFIG['MAINLIBS']"

LD_PRELOAD wouldn't change RbConfig::CONFIG['MAINLIBS'] output, it'd just forcefully inject jemalloc symbols into it.

In any case it appears that RbConfig::CONFIG['MAINLIBS'] doesn't contain anything about jemalloc anyway, even when statically built against jemalloc.

I'm not able to reproduce the issue in a local docker either.

I couldn't reproduce it either inside that x86_64 image: test suite passes, even when artificially stressing libv8 by throwing copious amounts of quickly hacked JS code processing to it (granted it was a real quick test).
