Hi,

This program will crash the poke:


```poke
var funs = [
  lambda void:
    {
      raise E_generic;
    },
  lambda void:
    {
      raise E_generic;
    },
];

for (f in funs)
  {
    try f();
    catch (Exception ex)
      {
        printf ("FAIL %s\n", ex.msg);
        continue;
      }
    print ("PASS\n");
  }
```
