I understand. I just can't figure out what's causing this. The call is a few nested templates and I don't understand why the type passed to the outermost one ends up as `void*` in the innermost one. > 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? I don't think the issue is RISC-V-specific. It's in two shared files (`xPageAllocator.cpp` and `zPageAllocator.cpp`). > Also, does the failure happen in release builds, or only (fast)debug builds?
