Since Rust 1.95.0, trying to build my app on Haiku OS fails with this error: With Rust 1.89.0 the build went through just fine! I suppose here "TLS" refers to thread-local storage rather than transport layer security What is causing this? Is this a bug in rustc or in the OS? Probably not a bug in my code, since the same code compiles (and runs) fine with Rust 1.95.0 on various other OS, including Linux, Windows, macOS and FreeBSD. In either case, is there any workaround, like specific rustc settings or changing my code? Best regards.
