I've gone ahead and filed Linux: Swift 6 LLDB/repl built with 5.10.1+lld crashes on evaluating Swift code · Issue #77243 · swiftlang/swift · GitHub for this: I'm able to reproduce this issue in the official Swift Docker images for both Ubuntu 24.04 and Fedora 39.
tl;dr:
| Linker | Swift 5.10.1 | Swift 6.0.1 |
