sass
Seg fault during development
Starting recently after some gem updates, seemingly randomly, saving a .scss file during development results in this segmentation fault:
/usr/local/bundle/gems/sassc-2.0.1/lib/sassc/engine.rb:42: [BUG] Segmentation fault at 0x0000000000000000
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]
I can't provide specific steps to reproduce because this is happening unpredictably, in any of the app's stylesheets.
This is a production Rails 6 app that has been stable for years (originally Rails 5). The app is Dockerized, and the development setup has not changed in some time. What other information can I provide to help diagnose this? I'm hopeful that this error will not appear in production (precompiled), but the severity of the error is disconcerting.
Also seeing this during a heroku build of an application:
/tmp/build_5e0a535a3d8650948298370ae436c71c/vendor/bundle/ruby/2.7.0/gems/sassc-2.4.0/lib/sassc/engine.rb:43: [BUG] Segmentation fault at 0x0000000000000000
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]`
Updating sass-rails (and using sassc-rails) has been doing this for many/all of my Rails applications
Same problem here.
/home/me/.rvm/gems/ruby-2.6.5/gems/sassc-2.4.0/lib/sassc/engine.rb:43: [BUG] Segmentation fault at 0x0000000000000000 ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]
I'm working on integrating a design at the moment and so changing styles quite a bit and it is happening almost every time I make a change. No problem with older Rails 5 projects only with a newer Rails 6 (with webpacker) problem.
I tried downgrading sprockets to 3.7.2 as that seemed to work for some people but it hasn't worked for me.
Any idea how we can get this fixed? It's manageable when only making the odd change but when actively working with styles it is a headache! :)
Getting this with a heroku build. I was able to deploy this app initially but now I'm getting Precompiling assets failed. Any direction on this issue?
I was using sematic styling and linking like
@import "semantic-ui"; @import "semantic-ui/collections/menu";
and once I removed that I stopped getting that error
Has anyone figured this out? I came back to a project and every time I run rails s it crashes on the first render.
FWIW, my seg faults with Sprockets 4 seem to be going away after disabling concurrent compilation (export_concurrent = false): https://github.com/rails/sprockets/issues/633#issuecomment-774762509
