v8 currently FTBFS on Rawhide and F28 because it triggers a new warning in LLVM 6, and uses -Werror so the warning is counted as an error: ../../src/base/macros.h:290:43: error: arithmetic on a null pointer treated as a cast from integer to pointer is a GNU extension [-Werror,-Wnull-pointer-arithmetic] return static_cast<T>(static_cast<T>(0) + x); ~~~~~~~~~~~~~~~~~ ^ "-Wnull-pointer-arithmetic now warns about performing pointer arithmetic on a null pointer. Such pointer arithmetic has an undefined behavior if the offset is nonzero. It also now warns about arithmetic on a null pointer treated as a cast from integer to pointer (GNU extension)." - http://releases.llvm.org/6.0.0/tools/clang/docs/ReleaseNotes.html Reported upstream as: https://bugs.chromium.org/p/chromium/issues/detail?id=820303
