Are capturing lambdas supported?

With the default configuration the following code segfaults:

```cpp
TEST_CASE("Delegate test with large capture")
{
int a = 0, b, c, d;
delegate::Delegate test([&a, &b, &c]()
{
a = 1;
});

test();

REQUIRE(a == 1);
}
```

Until I increase DELEGATE_ARGS_SIZE.
```cpp
#define DELEGATE_ARGS_SIZE sizeof(int) + sizeof(int *) /* + N */
```

So it seems to work when the capturing lambda only captures 2 words worth of memory. Is this working as intended?
Or should I expect lambdas of any size to fail at some point in the future for me?

Thanks!
