SegFault in pnoise2 when providing large seeds

I'm getting inconsistent segfault crashes when using seeds larger than 15000 (using consistent values for the other parameters). it's my understanding that seeds should be able to take integer values between -2^31 and 2^31 - 1, correct me if i'm wrong.

the following crashes for me consistently
```python
import noise
noise.pnoise2(0.2,0.2,base = 1000000)
```
