The fix for [JDK-8294031](https://bugs.openjdk.org/browse/JDK-8294031) was to make various error reporting functions `[[noreturn]]`. Is there perhaps a missing `[[noreturn]]` in the RISC-V code? Or is there some other statically apparent but never actually taken code path? Also, does the failure happen in release builds, or only (fast)debug builds? More details about the failure would be helpful.
