DenseMapSIMD Throws IndexOutOfRangeException inside Contains #28

Closed NightlyRevenger closed 1 year ago

NightlyRevenger commented 1 year ago

DenseMapSIMD Throws IndexOutOfRangeException inside Contains when small length was passed into constructor.

Minimum working example:

var fmap = new DenseMapSIMD<long, long>(1);
fmap.Emplace(0L, 0L);

var r = fmap.Contains(1);

The piece of code above throws IndexOutOfRangeException inside GetArrayEntryRef Most likely the reason is length instead of _length here:
