I just noticed debbie was set to run against 3.9 so if it was a 3.10 issue she wasn't testing. Checking on her. That said not sure why winnie isn't at rc2. Will retest on newly released 3.10 to see if still and issue.

Okay debbie ain't happy either after I flipped her to her GEOS master branch.

Same errors:

Fix regress caused by rounding differences
between GEOS 3.10 and older GEOS

Didn't notice pramsey had already done this for 3.1 branch at [ec7f996bc9537919ea900f2517ab6ceae78c2b70/git] and we did slightly differently. I will update with his changes to keep in sync.

In d1e8418/git:

Revise to agree with 3.1 branch. Closes #5012 for PostGIS 3.2.0
