invalid pointer error

[aborruso]

Hi, first of all thank you for this great tool.

I am taking the first steps and I started with this command:

quackosm --geom-filter-geocode "Roccafiorita"

It works but at the end I have

free(): invalid pointer
[1]    3139 IOT instruction  quackosm --geom-filter-geocode "Roccafiorita"

What am I doing wrong?

THank you

Hello @aborruso, sorry for the late reply.

From the logs you have provided, it seems like the operation worked properly (from the Python perspective), but there might be some internal problem with either Python installation or DuckDB installation on your machine. The free() call might be related to either C or Rust based dependencies and I have never encountered this error (library is tested on Ubuntu, Windows and Mac OS). It probably didn't release memory properly during operation, but logs indicate that everything went fine.

hello @RaczeQ in output I have this folders/files

Does that sound like a correct output? What debugging could I do?

Thank you

Yes, these are properly generated files:

• cache/0df...cb.json - output from the OSMnx library after geocoding Roccafiorita to geometry.
• cache/geofabrik_index.geojson - cached Geofabrik OSM extracts index
• files/b74...3e_nofilter_compact.parquet - the result of final operation (OSM features from the Roccafiorita region)
• files/Geofabrik_isole.osm.pbf - source ProtoBuffer file downloaded from the Geofabrik website which was used to read OSM data

If there was some error, you wouldn't see the third .parquet file, but since it exists, it means that operation finished successfully.

Here is my output:

Mine result is around 73 KB, so quite close to yours 93 KB (probably because of the QuackOSM version difference).

thank you
