Hello,

concerning the problem on DEC/Alpha machines**, I'm not sure that it is
a problem of CXML libraries, or at least not only that; it could be due
to the compiler version, perhaps coupled to the operating system
version.

I have the copper example running with correct results on a machine
(let's call it machine1) running CXML version 5.2 (XMDLIB6520) and f90
version 5.5 (DFABASE551).

On another machine (machine2), were I have an old version, f90 5.3  and
CXML 3.6, it compiles but the copper example stops with floating
invalid. If I link to the (static) library file of CXML 5.2 (which I
copied from machine1) the problem is still there. The executable
produced on machine1 doesn't work on machine2 (unresolved symbol:
for_check_mult_overflow64).
The executable produced on machine2 runs on machine1, but still stops
for floating invalid.


Both processors are of the ev6 family. 
The operating system version is not the same (machine1 runs Tru64 V5.1
732, machine2 runs Tru64 V4.0 1229).

Hope this will give some hints, 

Guido


** I'm talking of machines running Tru64, I don't know anything about
those running linux.
