It was the code from the CVS (i.e. 4.10.99).

In order to use setjmp & longjmp in the PowerPC port, patches are
needed for newlib-1.18.0. We  had discussions with Ralf about this in 
March 2009.
In the testsuites/samples/ , setjmp & longjmp are called.  If one used 
the prebuilt
gcc tools (i.e.  rpm) , setjmp & longjmp will crash. I had those patches 
done for
newlib-1.18.0 yesterday.   However, it is not tested for RTEMS 4.10 yet. 
I can send
the patch when it is all tested.  I am still patching the RHEL5 on an 
old, slow and
headless laptop.....
