Comment (by simonpj):

 Once more, I urge you ''not'' to try debugging a stage2 compiler, unless
 you have a great deal of time on your hands. Instead, compile the
 libraries and stage2 compiler without the optimisation; and then try the
 testsuite and nofib. These are small programs and much easier to debug.
