Kevin Hovsäter reported a crash in cli when running 'cargo run -po cli -- --bundle-path target/debug/Zed'. It was caused by unaligned pointer access in ipc-channel library; rustc started generating debug_asserts for pointer alignment starting with 1.70, which we have oh-so-conveniently upgraded to shortly before Kevin noticed a fix.
Rust 1.70 did not introduce this panic, it merely started triggering on UB that was previously ignored.
