Re: BUG #16665: Segmentation fault

I'm not really sure how to read that binary file.

I have uploaded to an s3 bucket and made it public.
Anyone should be able to access that file
https://s3.eu-central-1.wasabisys.com/union-backups/core_dump.gz

it's 2GB

If you have a link to a documentation of how I can read that file and get the stacktrace, I would be glad to give it a read.
