Apologies about my misleading statement about support for the OS. It doesn't seem to be receiving security updates anymore so I had assumed it reached end of life. Looking at the report, the crash happens after fork. There was a Ruby crash in the [past](https://bugs.ruby-lang.org/issues/13646) that happens when calling `getaddrinfo()` in the fork child. I sent Apple a bug report and they closed it as a duplicate, so I take it that they agree it's a bug in their system library. All they told me is that the bug I submitted is a duplicate with bug id 50511049 in their internal bug tracking system to which I have no access. They fixed the bug a few OS updates down the line. Similar to this crash, that crash happens in `libdispatch`. Anecdotally, it seems that macOS's support for fork without exec isn't great, especially in older versions. I wouldn't be surprised if this is another system library problem. A possible workaround for the crash might be running `bin/spring stop` and prefixing the `rails g` command with `DISABLE_SPRING=1 `. This should avoid forking the Ruby process. In any case, I still recommend upgrading to a newer OS. ---------------------------------------- Bug #17843: Ruby on Rails error[BUG] Segmentation fault at 0x0000000000000110 ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin15] (#42110) https://bugs.ruby-lang.org/issues/17843#change-91787 * Author: nayaronfire (kk nayar) * Status: Open * Priority: Normal * ruby -v: 3.0.1p64 * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- following tutorial https://www.youtube.com/watch?v=nlKIJfv50U0 On this command $ rails g scaffold Survey name:text laptop:binary os:text the following error was generated with the following instruction [BUG] Segmentation fault at 0x0000000000000110 ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin15] -- Crash Report log information -------------------------------------------- See Crash Report log file under the one of following: * ~/Library/Logs/DiagnosticReports * /Library/Logs/DiagnosticReports for more details.
