Cool, ever since that rachelbythebay article [1] I was wondering how different libcs handle the issue! Nice to see that someone else confirming the behavior of apple'c libc. It's not mentioned in the article, but while apple's libc seems to suffer from the use-after-free issue, if I'm reading it right it does seem to have locking for setenv/getenv [3] [1] https://news.ycombinator.com/item?id=37908655 [2] https://news.ycombinator.com/item?id=37952916 [3] https://github.com/apple-open-source-mirror/Libc/blob/master...

Doesn't musl have the same issue? https://github.com/JuliaLang/julia/issues/34726#issuecomment... I also wonder about OSX's libc. Newer versions seem to have some sort of locking https://github.com/apple-open-source-mirror/Libc/blob/master... but they free pointers so it's not safe from a potential use-after-free client side. but older versions (from 10.9) don't even have any locking: https://github.com/apple-oss-distributions/Libc/blob/Libc-99...
