Do the types in the declaration of XCreateWindow exactly match those in the 
system's Xlib.h.  Your test case is wrong for x86 because it uses "ulong" in 
the *.cs code and "unsigned long" in the *.c code.  Those aren't the same 
size.  Similar problems may be happening with the amd64 version.  Check the 
numeric types in the generated Xlib.cs and Types.cs files to ensure that the 
amd64 versions are correct.

I can perhaps diagnose this further if you send me the above generated files 
on an amd64 machine, together with the Xlib.h file, and the size of all int 
and long types from that amd64 machine.

If all of that checks out, then it is perhaps something in libffi.  Have you 
tried updating it yet?
