Seems to be related to sass/sassc-rails#58 (comment)

Happens when it hits any asset pipeline helper, like image-url()

See attached below for my full stack traces and crash reports:

glebm · 2019-10-19T04:39:41Z

See rails/sprockets#581 (comment) for a workaround

* During Heroku deploys we can build a new container successfully, but the release phase fails with a seg fault with similar output to sass/sassc-ruby#133 * After a lot of cross referencing between this app and a recent working example of Heroku containers (https://github.com/LBHackney-IT/report-a-defect) it worked until Standard.rb was added and bumped this gem. Setting it backwards until a new version can be made fixed the issue. * Tests run, including standard. And the page is styled correctly with it's assets precompiled. There doesn't _look_ to be a negative impact of removing reverting minor update.

Hitting the same backtrace on OpenBSD, sassc-2.2.1

rompic · 2020-04-19T13:23:34Z

I still hit this or something similar when trying to hunt a memory leak with mwrap
sassc-ruby 2.3.0 and rails/sprockets#630 do not fix it for me, neither does setting export_concurrent to false.

mechiland · 2020-05-03T00:59:05Z

Same issue here: sassc 2.3.0 + ruby 2.6.6 on Ubuntu 18.04.

ordinz · 2020-05-24T14:39:52Z

check out rails/sprockets#633

bogn83 · 2020-11-17T14:58:22Z

For us an update to sassc 2.4.0 which included an update of ffi from 1.11.1 to 1.13.1 fixed it.

sassc 2.2.1 brought a LoadError fix and 2.3.0 made the arch native flag default to false.

@rompic & @mechiland should you still encounter this issue you may try installing like this: bundle config --local build.sassc --disable-march-tune-native which is taken from this #146 (comment).
