I’m seeing crashes in the 3D subsystem. (Gallium? Glamor? Whatever other Mesa thing they have? No idea.) In the logs I find this:
malloc(): unaligned tcache chunk detected
And that’s why I still care about Rust and want to learn more about it, even though it’s giving me so much headache and I’ve given up so many times. Because Rust currently seems to be the only popular systems programming language that tries to eliminate these error classes.
And of course “the Rust experiment” in the Linux kernel has recently been concluded as “successful”, so that alone is reason enough for me:
