How is that a memory safety issue in Rust compiler? What point are we making here. Am I just too dense to understand, is how the hell is that a need unsafe issue? Or anything to do with compilers???
TFA discusses this in detail. The point is memory errors in the generated code. The generated code is an output the compiler. Thus the OP counts these against the compiler--after all, that's his project, those bugs are real, and those bug reports must be dealt with. His point is that the Rust borrow checker doesn't help at all with these bugs, and that matters when weighing the pros and cons of writing the compiler in Rust vs. Zig -- the languages are a wash for that category of error.
I do think this is a bit off, because miscompilations can produce all sorts of errors, not just memory errors, so it doesn't make much sense to categorize them as memory errors -- they are logic errors in the compiler. But the basic idea holds -- the choice of implementation language doesn't matter.
