Comment (by strk):

 I can reproduce locally with POSTGIS="3.5.0dev 3.4.0rc1-1231-g932e4936c"
 GEOS="3.13.0beta2-CAPI-1.19.0".

  What happens is that one of the `TopoGeo_addLinestring` calls (the one
 before the last in the testcase) makes the topology invalid. I'm working
 on reducing the testcase.
