Okay, I've determined that versions of LLVM/Clang before 19 crash when compiling this patch for some reason; it seems that both make check-world and make install will crash with the affected LLVM versions. Unfortunately, what matters seems to be the version of the linker/LTO optimizer, which I don't think we can check at compile time. I added a check for Clang>=19 which works at preventing the crash on my system. I think it's possible some unusual combination of clang/LLVM might still crash during the build, but I think this is a reasonable solution
