Segmentation fault in ST_Covers

[klette]

Hi, we've been experiencing segmentation faults (signal 11) in production lately, so I have been trying to debug what's going on.

The production query (ORM generated, so not the prettiest thing):

SELECT "installercost_costmodelcoveredarea"."id",
       "installercost_costmodelcoveredarea"."name",
       "installercost_costmodelcoveredarea"."code",
       EXISTS(
        SELECT (1) AS "a"
          FROM "installercost_costmodelcoveredarea" U0
         INNER JOIN "installercost_costmodel_covered_areas" U1
            ON (U0."id" = U1."costmodelcoveredarea_id")
         WHERE (U1."costmodel_id" = 'eddcec87-ae8c-4312-bb52-fac52c5c6ffe'::uuid AND NOT (U0."id" = "installercost_costmodelcoveredarea"."id") AND ST_Covers(ST_MakeValid(CAST(U0."geometry" AS geometry(GEOMETRY,4326))), ST_MakeValid(CAST("installercost_costmodelcoveredarea"."geometry" AS geometry(GEOMETRY,4326)))))
         LIMIT 1
       ) AS "has_encapsulating_parent"
  FROM "installercost_costmodelcoveredarea"
 INNER JOIN "installercost_costmodel_covered_areas"
    ON ("installercost_costmodelcoveredarea"."id" = "installercost_costmodel_covered_areas"."costmodelcoveredarea_id")
 WHERE "installercost_costmodel_covered_areas"."costmodel_id" = 'eddcec87-ae8c-4312-bb52-fac52c5c6ffe'::uuid 
 ORDER BY "installercost_costmodelcoveredarea"."code" ASC;

As mentioned this crashes the server, but only on some input.

I was able to reproduce the error locally using the production dataset, but I've not been able to create a minimal case.

I created a stack trace in GDB with symbols, but I don't have a debug build available:

Inspecting the memory I've extracted the two geometries (MultiPolygons). I have attached them, as one of the is quite large.

The only, maybe, smoking gun is that the last MultiPolygon has it's last element as EMPTY. So that might be something.

I've tried all combinations of ST_Cover-calls using these two geometries, but I'm not able to reproduce the crash outside of the query posted above. So maybe some optimization passing in a nullptr?

I've tried disabling both JIT and parallel workers, but to no avail.

hmm someone mentioned a similar issue to me and couldn't track down what was causing it and had the same issue of not being able to replicate outside of a production environment. But they were running GEOS 3.7 and similar issues have been fixed since then. As I recall the trace looked very similar involving geos::geom::prep::PreparedPolygonPredicate.

I noticed you are running GEOS 3.10.2. Any chance you can upgrade to GEOS 3.10.3 to rule out the issue has already been fixed? Looking at the issue list in 3.10.3, ​https://libgeos.org/posts/2022-06-03-geos-3-10-3-released/ I doubt your issue has been fixed though.

I've flipped this to PostGIS GEOS, since it sounds like a GEOS issue. If upgrading to 3.10.3 still doesn't fix it, then you should report to the GEOS issue tracker over here -- ​https://github.com/libgeos/geos/issues or report anyway if you can't upgrade

This is a GEOS issue, and is present in main (3.12). The area2 geometry is a MultiPolygon with an EMPTY element. It seems the prepared covers operation crashes on empty elements.

This is a JTS issue as well. I'll fix it there, and then in GEOS.
