      Bummer. I do like the protection against crashes, but using assembly
      makes it very difficult to compile Vim on various platforms (64 bit

      It appears your code also catches a crash in the called function. That
      was not really required. Would it be possible to avoid the assembly
      code when we only want to check the returned pointer? There actually is
      a function for this (to check the validity of a pointer), but I couldn't
      make it work.

      161. You get up before the sun rises to check your e-mail, and you
      find yourself in the very same chair long after the sun has set.
