Help needed with debugging

[Fred Kiefer]

I am getting rather strange results when running a GNUstep test
application. Here my gdb buffer:

address@hidden:~/GNUstep/Examples/TestApp3a> openapp --debug ./TestApp3.app/

So there is a static variable numberMap in NSNumber.m that is at once
set and not set. Does anybody out there have an explanation for this and
even better a workaround for this problem?

This same test application used to work and other applications still
continue to work well. Although any real problem in base should break
them all.
