Because the default CRC-32 algorithm occasionally returns duplicates I use MD5.
I noticed that MD5 does not uses geometry.

Tested in 2018.1.0.1: same problem.
@david_r: in CRCCalculator use _creation_instance as attribute and you get the duplicate. Change MD5 to CRC32 and it works fine.

In 2020.1.0.0 still not corrected. When using Selected Attributes Geometry is not used, resulting in duplicate crc value. Only when using MD5

David, you did not include the _creation_instance attribute in the CRCCalculator.
In 2022.0 issue still present
Same problem in 2021.0. Works if no selected attributes. But when adding one or more attributes geometries is no longer used when the MD5 is calculated.
