I would start by reading the output in your Web server's error_log. 
Internal Server Error just means 'something went wrong' -- the details 
are in your error log.

Could you show us your hello world code and tell us how you're compiling 
etc? Without more details it's hard to say what's going wrong.

It's a typical hello world program:

import std.stdio;

void main(string[] args)
{
	writeln("Hello world!");
}

I also tried using printf instead of writeln. I'm compiling it with dmd test.d.
I'm using dmd v2.046. I'm compiling the c program with gcc -otest2 test2.c.

And how are you interfacing each app with cgi? There could be some 
subtle difference there which is doing it, that app on its own looks 
fine and works here.

It works now after i added 

writeln("Content-Type: text/plain;charset=us-ascii\n\n");

I didn't know this is required, i have never used CGI before. I copied c
example from some cgi tutorial and forgot to include that line in the D
program. I'm sorry for wasting your time.

And I guess this should really be writeln("Content-Type:
text/plain;charset=utf-8\n\n") for D.

Just a guess, but maybe the difference of your C and D programs is in 
return value, which can be differently interpreted by CGI host. try 
returning 1 or 0 from the program.

It should be ok. If there is no return statement, a D program returns 0 
for successful exit, and non-zero for error.

This point has been stressed in Andrei Alexandrescu's "The Case for D" 
article when comparing the "hello world" programs of some languages.
