I don't quite know how you got your error message, but this is the 
message I came up with (Windows version):

   Assertion failure: '0' on line 658 in file 'statement.c'

   abnormal program termination


It's not very descriptive, either.

Here's the code I used (so that everyone can play along at home):


void main()
{
     char[] iterMap;

     foreach(char[] key, int; iterMap) /* missing identifier before ; */
     {
         printf("key = %.*s\n", key);
     }

}

Shouldn't that be?

void main()
{
    char[] iterMap;

    foreach(int i, char key; iterMap)
    {
        printf("key = %.*s\n", key);
    }

or even simpler?

void main()

    char[] iterMap;

    foreach(char key; iterMap)
    {
        printf("key = %.*s\n", key);
    }

Actually, there's a semantic bug here:

Do you want to go cycle though chars or strings?

I mean you should either use:

printf("key = %c\n", key);

or (with the appropriate changes in the for loop)

char[][] iterMap;

I realize that my code was invalid. I think Ant's point was that 
nonsense was emitted by DMD instead of a helpful error message. (Hence 
the subject "bug compiler MESSAGE".)

I'm not sure what Ant was trying to do. I suspect he figured out how to 
accomplish his goal, but he was trying to clue Walter into a 
circumstance where the compiler produces an odd message. I spent a 
little time completing his example to try to reproduce his problem. I 
though my code had an interesting result, too, so I shared it. Sorry, if 
I was unclear in my first reply.

that's it!
Do he have a better subject?
(I'm sure I'll find more...)

Yes, thank you, I don't require assistance with this problem,
sorry if I mislead you...

I sorry two mistakes on my post
1. it's an associative array,
2. I changed the code before posting but forgot to copy the compiler
message again:

foreach(char[] k, TreeIter ; iterMap)
{
printf("k = %.*s\n", k);
}
// it has "k" instead of "key"

Now, I've seen it for myself (WinXP). Wow, that may be the strangest 
error message I've ever seen.

Here's the code I used:

alias int TreeIter;
void main()
{
     char[char[]] iterMap;
     foreach(char[] k, TreeIter ; iterMap)
     {
         printf("k = %.*s\n", k);
     }
}

You mean something like the following?
void main()
{
    char[][] iterMap;

    iterMap.length = 10;
    iterMap[0] = "hi";

    foreach(char [] key; iterMap)
    {

It's a DUI program (leds).
