Here is a piece of code reproducing the error:

OGCSphericSystem distance: (OGCPoint xy: #(8.426901532959166 48.942219049707404) ) toPoint: (OGCPoint xy: #(8.426901532959166 48.942219049707404)).

It looks like there is some imprecision somewhere which ends computing the arcos of 1.0000000000000002.
Which fail because the value is expected to be between -1 and 1
