It's massive, and several gcc versions have to be blacklisted. The clang restrict bug is still not fixed, it never worked.
rustc was never memory-, type- nor concurrency-safe.
Compared to the amount of code that people compile and the number of bugs seen and fixed in that code, that is a tiny number of bugs. I wouldn't say it's "never" a compiler error but when you find a bug in your program, it's almost certainly not the compiler's fault.
