Anyway, the failure count is very low, a half-dozen from hundreds is fine
(and if they didn't write tests, that isn't our problem...).
What would be especially interesting is to see whether OverlayNG resolves
the various overlay robustness issues reported in R-sf issues.
E.g.
https://github.com/r-spatial/sf/issues/794
(I had a local copy of the all.rds file)
all %>% st_intersection -> o
Error in CPL_nary_intersection(x) :
Evaluation error: TopologyException: found non-noded intersection

45.466850983501708.
all %>% st_set_precision(1e8) %>% st_intersection -> o
Error in CPL_nary_intersection(x) :

library(sf)
Linking to GEOS 3.9.0dev, GDAL 3.2.0dev-b51dc28ab7, PROJ 7.2.0
p1 <- readRDS("p1.rds")
p2 <- readRDS("p2.rds")
p3 <- sf::st_difference(p1, p2)
so now runs with Overlay-NG and sf's default 0 precision, but sf has also
changed since late 2017.
https://github.com/r-spatial/sf/issues/936
Error in CPL_nary_intersection(x) :
Evaluation error: TopologyException: Input geom 0 is invalid:
Self-intersection at 314406.13208707399 -5762352.8343122564.

Cases 794 and 936 are all-by-all intersections, and as noted in the latter
issue, the problems occurring differ by input order.
Please ask off-list if someone needs all.rds from 794.
