Failure in cpukit/score/src/rbtreeextract.c if RTEMS_DEBUG is defined

[Heinz Junkes]

I'm starting an EPICS IOC. Loading works if I don't set RTEMS_DEBUG.
The loaded images are similar in size.
I have not changed anything in the EPICS software. I still have the problem that I do not understand
how the freebsd dhcpcd works and therefore wanted to set RTEMS_DEBUG to get more detailed output.
