Anti-aliasing happens from the outside side of the spline, which is actually happened to be an inner side of your "buggy" spline. Just switch direction of the spline and anti-alias will work fine.

Similar issue will happen with feather as well.

It is a but annoying, but it is how things currently work. Improvements are welcome, but they are happening outside of the bug tracker.

So thanks for the report, but closing it now.
