======================================================
                 CORE DUMP ACTIVATED                  
======================================================
[*] JS Payload dumped to -> core_dump.js
$ 

==

That core dump is a lifesaver. It shows us exactly where the AST generator
derailed and swallowed its own tail!

Look at this line from your generated `core_dump.js`:

```javascript
(filename = (("tmp_eval_" + _this.random = function(9999999)) + ".c"));

```

The VM literally tried to parse `random(9999999)` as a **function definition**
instead of a function call, assigning a function to `_this.random` in the
middle of a string concatenation!

### Why did this happen?

It comes down to a strict rule in traditional LPC dialects (which your
compiler enforces): **Inline variable initialization is illegal.**

In modern languages, you can write `string filename = "foo";`. But in
old-school C and LPC, variables *must* be declared at the top of the block,
and assigned later.

Because we wrote `string filename = "tmp_eval_" + random...`, the lexer saw
the `string` keyword, held onto it, and when it hit `random()`, it thought we
were trying to declare a nested function named `random` that returns a
`string`. When it finally hit the semicolon `;`, the parser realized it was
actually a variable declaration, panicked, and blindly popped the AST tokens
off the stack, corrupting the generated JavaScript.

### The Fix

We don't need to rewrite the compiler. We just need to write valid, strict LPC
in our REPL script by moving all variable declarations to the top of the
function and assigning them separately.

Replace the contents of **`tests/repl.c`** with this strict-compliant version:

```c
/ tests/repl.c
void create() {
    printf("Type 'help' for a list of commands.
");
}

void process_repl_command_line(string input) {
    // 1. Declare ALL variables at the top of the block
    string cmd, arg;
    string filename, src;
    object ob;
    mixed res;
    
    // 2. Execute logic
    if (sscanf(input, "%s %s", cmd, arg) != 2) {
        cmd = input;
    }

    if (cmd == "help") {
        printf("Available commands:
");
        printf("  help          - Show this message
");
        printf("  time          - Display system time
");
        printf("  md5 <string>  - Hash a string
");
        printf("  eval <lpc>    - Evaluate LPC expression dynamically
");
        printf("  clear         - Clear the screen (handled by frontend)
");
    } 
    else if (cmd == "time") {
        printf("System uptime: %d seconds
", uptime());
        printf("Current time: %s
", ctime(time()));
    }
    else if (cmd == "md5" && arg) {
        printf("MD5('%s') = %s
", arg, md5(arg));
    }
    else if (cmd == "eval" && arg) {
        // Assign the previously declared variables
        filename = "tmp_eval_" + random(9999999) + ".c";
        src = "mixed do_eval() { return (" + arg + "); }
";
        
        if (write_file(filename, src)) {
            ob = clone_object(filename);
            if (ob) {
                res = ob->do_eval();
                printf("Result: %s
", res);
                destruct(ob);
            } else {
                printf("Error: Failed to compile expression.
");
            }
            rm(filename); // Clean up the VFS
        } else {
            printf("Error: Failed to write temp file to VFS.
");
        }
    }
    else if (cmd == "") {
        // Do nothing on empty enter
    }
    else {
        printf("Unrecognized command: %s
", cmd);
    }
}

```

Run `node build_web.js` again. The compiler will now cleanly parse the
`random()` and `clone_object()` calls as standard executions instead of
definitions, and the `eval` command will be fully armed and operational in the
browser!
