[Taginfo-dev] New taginfo -- segfault

[David Paleino]

Hello people,
I just updated the Italian instance of taginfo [0], and now tagstats segfaults.

  [0]: http://taginfo.hanskalabs.net/

While I could drop all my "customizations", and put them into the config.json,
my limited C++-fu doesn't let me understand what's going on here:

$ ./tagstats -d -t 47.2 -l 6.4 -b 35.2 -r 18.6 ~/osm-dumps/italy.osm.pbf
> taginfo-db.db 
sizeof(value_hash_map_t) = 88
sizeof(Counter) = 12
sizeof(key_combination_hash_map_t) = 88
sizeof(user_hash_map_t) = 88
sizeof(GeoDistribution) = 16
sizeof(KeyStats) = 320

string_store: chunk_size=10MB chunks=1 memory=10MB bytes_in_last=0kB
VmPeak:	  125592 kB
VmSize:	  125592 kB
init done

(roughly, "Segmentation error").

Running it through gdb gives this, which is quite obscure to my eyes:

Any hint on what could've gone wrong? I'm currently at

Thank you very much,
