`CICrashAt` triggers an assertion during compilation where as I need an assertion or guarantee in VM code called from JIT compiled code. To be completely reliable, this needs a runtime entry point to `assert`, `guarantee` or `fatal` that can be called from compiled code. JVMCI has such an entry point for `fatal` (`JVMCIRuntime::vm_message`) but without Graal in the JDK, it's hard to write a test that uses it. I've done such testing manually so am confident that it works.
