Well, unfortunately ANDREW_MALLOC_ENV will cause problems.  Tryrunning
bush for example.  You can work around the problem by setting
theMALLOCTYPE environment variable to the value "3.1".  You can apply
thefollowing patch to atk/apps/runapp.c to permanently "fix" the problem.

      initClass();

These problems will be fixed "for real" in the next release of Andrew.
