KdTree assert out of range on MSVC

[AlexeySmolenchuk]

I'm compiling this project with the MSVC. In debug mode tests asserting with Expression: vector subscript out of range for &_ids[n+size]

    std::nth_element(&_ids[n], &_ids[n+left], &_ids[n+size],
		     ComparePointsById(&_points[0].p[j]));

here
https://github.com/wdas/partio/blob/main/src/lib/core/KdTree.h#L328

I know the algorithm never reaches the _ids[n+size] element, but I can't persuade the compiler.

Thank you

I'm not familiar with MSVC so I can't help much with that aspect.

I do see that we use pragmas to disable certain warnings for MSVC:

partio/src/lib/core/KdTree.h

Line 335 in 8d9832e

#ifdef _MSC_VER

Maybe try adding a similar pragma to silence the warning you're seeing?
