Darn. Yes.. one min, will push.. Sorry about the noise. (thought that the fact that it failed on linux meant it wasnt a diagnostic, but it is..)


  product(bool, ForceUnreachable, false, DIAGNOSTIC,                        \
          "Make all non code cache addresses to be unreachable by "         \
          "forcing use of 64bit literal fixups")
