I just tried to get this example to work:

It kept crashing for me with a 'privileged instruction' error
when the function 'bar' was executed. Finally I removed the
call to writefln and voilà it finally works.
So why does it fail? I assumed the standard library functions
should all work.
I'm compiling with "dmd -shared -m64 -debug" and link against a
C++ DLL that was built with VS2019. Should the D DLL not
contain everything to be self-sufficient to use it's entire
runtime functionality?
And if not, what other functions might be problematic?
The example links objects statically. You may be experiencing
additional challenges with crossing DLL boundaries. I have not
yet used DLLs, but did you initialise the D runtime?
