Segfault while trying to access null-objects.

I'm experiencing the same issue with haxelib mod_tora and git neko: http://haxe.org/forum/thread/3395#nabble-td6791774
Haxe code to reproduce:

```
var q : Dynamic = null;
q.some;
```

For the first attempt to access null object i get segfault message sent to my browser from my module:

```
Error : Segmentation fault
Called from a C function
Called from fst/Fst.hx line 17
Called from ? line 1
Called from D:\Projects\haxe/std/neko/vm/Module.hx line 52
Called from Tora.hx line 333
Called from D:\Projects\haxe/std/neko/vm/Loader.hx line 154
Called from D:\Projects\haxe/std/neko/vm/Loader.hx line 132
Called from Tora.hx line 479
```

Then i hit 'refresh' in browser and for the second attempt:

```
Error : Segmentation fault
Called from Tora.hx line 483
```

And the last try:
in browser: `Error : Connection Closed`
in terminal:

```
$ haxelib run tora
[2013-10-31 11:58:36] Starting Tora server on 127.0.0.1:6666 with 32 threads
Segmentation fault (core dumped)
```

At this point my web service is completely broken because of tora shutdown :)

My system: Ubuntu 12.04 32bit

Is it possible to fix this issue without disabling JIT?
