The post in question had early empirical data comparing bug reports from Node, Bun and Deno. It wasn't the main focus of the article, and I would love to see a deeper dive, but it showed that Bun had almost 8x the amount of "crash" or "segfault" bug reports on Github as Deno, despite having almost the same amount of total issues created. (4% of bug reports for Deno are crashes, 26% of bug reports for Bun are crashes).

This matches my experience with the runtimes in question—I tried Bun out for a very small project and ran into 3 distinct crashes, often in very simple parts of the code like command line processing. Obviously not every crash / null-pointer dereference is a memory safety issue, but I think most people would agree that Zig does not seem to make bug-free software easier to write.
