I am trying to get the m68k port working.  I'm almost there, but Runtime
has a problem.  If I use -vmdebug RESERROR, I get (tail end):

      0x11a048 entering process class java/lang/Runtime 1->5
      0x11a048 leaving process class java/lang/Runtime -> success

          0x11a048 entering process class kaffe/lang/MemoryAdvice 9->11
          0x11a048 leaving process class kaffe/lang/MemoryAdvice -> success
          0x11a048 entering process class kaffe/lang/MemoryAdvice 9->11
          0x11a048 leaving process class kaffe/lang/MemoryAdvice -> success
        0x11a048 leaving process class kaffe/lang/MemoryAdvice -> success
        0x11a048 entering process class java/lang/Runtime 9->11
        0x11a048 leaving process class java/lang/Runtime -> success
      0x11a048 leaving process class java/lang/Runtime -> failure

So, Runtime gets moved all the way to state 11 successfully, then fails.
Afterwards, soft_fixup_trampoline throws a SIGSEGV.

Under what circumstances can a class that makes it to state 11 successfully
fail?
