Cross-compilers in general are expected to work, but only basic testing has been done. Bare-metal targets have some basic betterC testing, but we only test without druntime. We never tested druntime or stripped-down druntime on baremetal targets. Compiler crashes are certainly bugs and should be reported. Druntime requiring more changes now is sad, but not really unexpected as I don't think anyone in the druntime team focuses on embedded targets. I guess most people working on bare-metal completely reimplement a custom runtime or use betterC with the C runtime only. -- Johannes
