@bascule @thisismissem I would probably replicate the same inline assembly that Ruby uses; that (when used with a stack slot) clearly marks the stack slot address as escaping, whereas I'm not quite so sure about volatile_read

@tenderlove it seems like somebody could build a reusable library providing a rb_gc_guard!() macro with the same function, no?

Aaron Patterson ✅

@whitequark @bascule @thisismissem ya, definitely. My "bigger issue" is that people writing native extensions -- including ones written in Rust -- need to grapple with the machine code the compiler generates. C is already famous for being unsafe, but Rust has the same "unsafety" when used in this context despite its fame for being "safe".
