If you compile the Java parts of the library with -fcheck-references, it
should work.  This is something you have to set up as part of the port,
as it is decided at (libgcj-) configure time.

This won't help with the native code.  IIRC in the end we just gave up
on that; if you wanted real correctness you would have to add a null
check at every dereference in the C++ code.  I believe Andrew had a g++
patch to do this in the compiler, but it was rejected.
