Have you checked the issue tracker?

Can you be any more specific? What kind of problems?

A DLL in D is loaded into a Python program, but not recognized 
later. It says: "NoneType doesn't have method called..." It's 
only on this machine (or processor?). I recompiled it on the 
machine, but I still get the same error. Unfortunately, we only 
have Intel processors, so I cannot test it on other AMD 
processors.

That's an error in your Python code.

I wish it were an error in the Python code so I could fix it, but 
it works on all other machines (at least those with Intel). It's 
only on the HP625 with AMD that this error occurs. Another DLL 
(which isn't mine) also failed to load, although with a different 
error message. It might be just this particular model, or AMD, I 
dunno. I couldn't find anything about it on the internet.

Atm I'm using dmd 2.067.1, maybe compiling with GDC or LDC will 
fix it.

That sounds more like its the software installed on the machine 
and not the processor. Are you sure that all microsoft runtime 
libraries are installed? If you did use the vs 2012 linker to 
create the D-dll you need to install this redistributable 
package: 
http://www.microsoft.com/en-US/download/details.aspx?id=30679

Did you run Depends on the dll? Usually depends will tell you why 
the dll does not load: http://www.dependencywalker.com/

Thanks, I will look into it.

The problem is that I don't have the machine anymore (had to 
return it to user). The weird thing is that the DLL loads 
correctly (else there would be an error message in the log file), 
but is a NoneType (i.e. null) when methods are called (e.g. 
mydll.getSomething()). If it were not loaded, it wouldn't even 
come to the point at which it calls functions in the DLL.
