New description:

 berrie64 which also does crasher tests seems to have gone thru fine
 (though I just checked and she's only testing GEOS 3.12.0 so have to up
 that), so maybe this only affects GEOS 3.13.

 I'm running with a week old geos, and will test after my latest is
 rebuilt.

 I'm surprised GEOS even works with triangles.  When did this happen.
 Should it be erroring out, or does GEOS now support triangles?

 This is running with
