Is it possible that this is related to [ruby-talk:153006]?  I'm
wondering whether the real difference between GCC3.3 and GCC4 on OSX
is that the latter compiles 64-bit by default.  Then our problems have
at least the following in common:

  1. DRb
  2. big-endian (SPARC in my case)
  3. 64-bit

In my case, I can reproduce with the Sun compiler and multiple GCC3
versions on Solaris 8 / SPARC.
