var theCArray *C.YourType = C.getTheArray()
length := C.getTheArrayLength()
- slice := (*[1 << 30]C.YourType)(unsafe.Pointer(theCArray))[:length:length]
+ slice := (*[1 << 28]C.YourType)(unsafe.Pointer(theCArray))[:length:length]
```
It is important to keep in mind that the Go garbage collector will not interact with this data, and that if it is freed from the C side of things, the behavior of any Go code using the slice is nondeterministic.
