Fun defining classes (I didn't verify with a compiler that I got this error wrong, forgive me):
A.h:

 cpp Syntax (Toggle Plain Text) 
#pragma once
// The preceding is a VS macro, shut up :P
#include "B.h"
 
class A
{
    B* b;
};
#pragma once
// The preceding is a VS macro, shut up :P
#include "B.h"

class A
{
    B* b;
};

B.h:

 cpp Syntax (Toggle Plain Text) 
#pragma once
 
#include "A.h"
 
class B
{
  A* a;
};
#pragma once

#include "A.h"

class B
{
  A* a;
};

whatfun.cpp:

 cpp Syntax (Toggle Plain Text) 
#include "A.h"
#include "B.h"
 
int main()
{
  A a;
  B b;
}
#include "A.h"
#include "B.h"

int main()
{
  A a;
  B b;
}

Fail! Does not meet the criteria (compile error, runtime error, or general potential to cause havoc).
ErrorCount--;
(can I take #14, since ErrorCount is as yet undefined?

)

I get:

(Toggle Plain Text)

[Linker error] undefined reference to `WinMain@16' 
ld returned 1 exit status

Is that not a compile error?

16) Arc

 lisp Syntax (Toggle Plain Text) 
(def function ()
          (cons 1 (function)))
(def function ()
          (cons 1 (function)))

Consing is (or should be) a fairly expensive operation for memory.

causes a java main thread exception error

if the array is defined in the main method
