Add a flag to toggle -Zbuild-std, and default to using it

24

By default, all the debug assertions in the standard library are compiled out, and the only way to get them back is `-Zbuild-std`. Even generic debug assertions can catch code...

`read_packed_fixed` converts a `&[u8]` to a `&[T]` without checking that the incoming reference satisfies the alignment of the outgoing reference. Since references guarantee that they are properly aligned and both...

I don't really understand what's going on here. All I really know is that I ran into one of the standard library's debug assertions when running some of the examples...

Avoid lossy ptr-int transmutes by using AtomicPtr

1

This project looks pretty inactive, but it is still used very widely by the ecosystem and Miri detects UB in it that looks unambiguously bad to me, so that's why...

Suspiciously large seek offset results in failed test

# Description This crate does not build with the latest beta, which means it will not in its current state build with the next stable. This is due to the...

Installations instructions don't work

2

In most places the project is called `yaiouom`, but the installation instructions call it `yaoioum`. I only see a `yaiouom-checker` on crates.io, and no `cargo-yaiouom`. I'm unsure of where the...

[crater experiment] Turn on debug assertions

7

The standard library has a lot more debug assertions since https://github.com/rust-lang/rust/pull/92686 which also found and fixed some UB in the compiler using them. It has been suggested that as a...

Add TCP keep-alive?

8

I'm currently working through what to do about a codebase that uses `ureq` and is suffering from what looks like a very occasionally unresponsive server. I'd like to toggle on...

Even nicer errors from assert_unsafe_precondition

13

For example, now running `cargo test` with this patch I get things like: ``` $ cargo +stage1 test Finished test [unoptimized + debuginfo] target(s) in 0.01s Running unittests src/lib.rs (target/debug/deps/malloc_buf-9d105ddf86862995)...

clang::source::SourceRange::tokenize can construct a slice with a null pointer, which is UB

1

This is detectable through the standard library's debug assertions, which are currently only usable on a nightly compiler with `-Zbuild-std`, or if you build your own compiler and standard library...
