All the JIT engines were made compatible with PaX MPROTECT on NetBSD. There will be few remaining failures in MemoryBlock (or similar class name) as they are testing W|X protection. I recall that there were 2 cases where something broke because of environment setup, like unexpected libstdc++ for clang/NetBSD rather than hardcoded libc++. I've not been testing the exact 6.0 release so the exact number of failures will wary. Probably below 20?
