Rider backend crash. MacOs. Crash produced by system 'ulimit -c unlimited'

Problem

Rider crashes reporting the "Critical Error Has Occurred" error. How to capture a crash dump on MacOs?

Answer

Follow the steps below:

1. Core dumps are located in /cores directory by default, therefore, it is necessary to allow non-root users to write to /cores, and set the sticky bit:

   sudo chmod o+w /cores
   sudo chmod +t /cores
   

2. Run the command ulimit -c unlimited. This command will only affect the processes spawned from the same shell session.

   Verify that it says unlimited when you query ulimit -c.

3. Check what is inside the folder /cores via running ls /cores

4. Then run Rider from the console and wait until it crashes. Rider can be started from the terminal with /Applications/Rider.app/Contents/MacOS/rider for standalone installations. In the case of the Toolbox installation, open Settings for the problematic version of Rider and copy the installation location from there, then start Rider using a path to the executable, for example: ~/Applications/Rider\ EAP.app/Contents/MacOS/rider

5. Find a newly created dump in the /cores directory and archive it.

6. Upload the archive to the Uploads Service and share the Upload ID (shown at the end of the upload process) in the corresponding YouTrack issue, Support request or thread.
