Segfaults in PHP are highly unusual. The language definitely has warts, but it's extremely well tested and usually doesn't crash in production, unless you're using unstable extensions or pre-release versions.

There are lots of projects out there that do not follow semver for their releases; that doesn't mean it isn't stable in itself. Having said that, every PHP release at least has proper change logs so you can safely migrate to a new version.
