Euphoria 4.0 and diamond

Hello,
there is a small problem with the diamond library of Mike Nelson (found in the archiv) and Euphoria 4.0 rev 1387.
I moved the include files into the demo folder and changed in diamond.e the words entry to Entry. I also changed in animal.e the first include statement to: include diamond.e.
If I now run demo.ex or event.ex I get this error:
D:\Euphoria\diamond\Demo>exwc Demo.ex
Fatal run-time error:
third argument of find_from() is out of bounds (0)
The instruction at 0x004cff93 referenced memory at 0x00000004.
The memory could not be written.
Exception fielded by 0x004dd3a0 ...
Running demo.ex or event.ex with eu.ex will show this:
D:\Euphoria\diamond\Demo>exwc c:\EUPHORIA\SOURCE40\eu.ex demo.ex
c:\EUPHORIA\SOURCE40\fwdref.e:264 in procedure patch_forward_variable()
third argument of find_from() is out of bounds (0)

> See ex.err
Press Enter...
I see that you have a lot of test programs for Euphoria 4.0. How do you build a test program for this case? What would be the best way to create a test program at all? Since some time there is a different behaviour in a special case with the use of type object (machine level exception error), but I do not know how to shorten the code in my application.
About benchmark with the diamond library:
speedtst.ex with exwc 3.1.1:
Enter the number of iterations (100-1000000): 100000
100000 iterations of Diamond set_property(): 0.110000
100000 iterations of Diamond get_property(): 0.090000
100000 iterations of Diamond call_method(): 0.250000
100000 iterations of Diamond constructor: 1.570000
100000 iterations of Diamond copy constructor: 0.260000
100000 iterations of Diamond destructor: 0.310000
Done. Press any key to exit.
speedtst.ex with exwc 4.0 (rev 1387)
Enter the number of iterations (100-1000000): 100000
100000 iterations of Diamond set_property(): 0.188000
100000 iterations of Diamond get_property(): 0.124000
100000 iterations of Diamond call_method(): 0.344000
100000 iterations of Diamond constructor: 2.340000
100000 iterations of Diamond copy constructor: 0.374000
100000 iterations of Diamond destructor: 0.374000
Done. Press any key to exit.
I did not yet try, but would speedtst.ex run faster if I would use public instead of global in the library?
