[Taginfo-dev] New taginfo -- segfault

[Jochen Topf]

Hi!

I am not sure I understand. Are you running an old tagstats or are you running
the new one? You should run the current tagstats (because taginfo needs all
the statistics it generates) and compile it yourself.

The biggest changes in tagstats a few months back were the statistics for tag
combinations and the distribution maps for ways. Both mean that tagstats needs
more memory. Maybe you are running out of memory.
