If it's reported twice, it is because runtime_error() is called twice.
The exceptions are when the driver object cannot be compiled, or when an
error occurs within driver::runtime_error().  Such errors may cause a
duplicate errormessage in some cases because DGD becomes confused when
errorreporting isn't working.

I'm sorry, but I can only judge the code as it is, or as it is illuminated
by comments.  If there are certain bugs that you do not want me to bring
up, please let me know in advance. :)

Actually, further inspection shows that clone() isn't called from
telnet_connect().  But it looks as if you call compile_object() from
all over, including clone(), and that is not correct -- the object
should only be cloned when it doesn't exist already.

The same problem occurs in driver::inherit_program() -- the object
to be inherited is recompiled every time, even if it already exists.
