I haven’t gone so far as to create a dataset, but you can use GitHub search to quickly peruse the top open source Zig repositories: https://github.com/search?q=+language%3AZig+stars%3A%3E1000&....

All of them, with the notable exception of tigerbeetle, a financial transactions database, have issue trackers which are littered with users reporting segfaults. I don’t really know if it’s more common than in popular Rust repositories, but this is my highly anecdotal, qualitative investigation.

What worries me is that when you dig into specific issues for root causes, there seem to be a lot of different root causes and not a lot of obvious fixes. And segfaults are just the tip of the iceberg, the most obvious memory errors. I don’t think people are reporting heap corruption in the same way, if ever.
