[postgis-devel] Postgres dies on ST_MakeValid

[Tom van Tilburg]

Postgres says:
"...pure virtual method called
terminate called without an active exception ..."
before dying

Fresh postgis build:
"POSTGIS="2.5.0dev r16508" [EXTENSION] PGSQL="100" GEOS="3.6.2-CAPI-1.10.2
4d2925d6" SFCGAL="1.3.1" PROJ="Rel. 4.9.3, 15 August 2016" GDAL="GDAL
2.2.3, released 2017/11/20" LIBXML="2.9.4" LIBJSON="0.12.1"
LIBPROTOBUF="1.2.1" RASTER (sfcgal procs from "2.5.0 (...)"


I can only reproduce when outputting the binary geometry, WKT doesn't give
this problem:

SELECT
ST_MakeValid(ST_MakePolygon(ST_GeomFromWKB('\001\002\000\000\000\011\000\000\000b\020X9

\211A\340\235I\034A')))

Output of ST_Isvalidreason gives "Self-intersection[92115.5120743143
463462.206937431]"

Best,
 Tom
