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

Problem

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

Answer

Follow the steps below:

1. The location of core dumps is specified in the /proc/sys/kernel/core_pattern, please be sure it will not be piped to another program by |/path/to/program pattern, otherwise you have to reconfigure it to /tmp directory using echo "/tmp/core.%e.%p" > /proc/sys/kernel/core_pattern, and restore the previous core_pattern later
2. Run the command ulimit -c unlimited
3. Check the directory specified in your core_pattern file (usually it is /tmp/ or current working directory).
4. Then run Rider from the console and wait until it crashes.
5. Find a newly created dump in the appropriate 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.
