Bizzare ReadOnlyMemoryError() causing segfaults with a quadratic bspline

I'm getting some weird intermittent `ReadOnlyMemoryError`s using interpolate as`interpolate(complexVectorToInterpolate, BSpline(Quadratic(Reflect())), OnGrid())`. It doesn't happen every time, but sometimes when it happens inside a function, julia suffers a segfault. I switched to `interpolate(complexVectorToInterpolate, BSpline(Linear()), OnGrid())`, and that doesn't seem to be having the same issues. I seem to have had some success if I run `interpolate(randn(1532), BSpline(Quadratic(Reflect())), OnGrid())` immediately after `using Interpolations`, but this is most certainly a hack I'd rather not leave in.

The result from the segfault follows:
```
