[Tile-serving] [osm2pgsql] Segmentation fault (#290)

[Vincent]

Hello,

I have segfaults while osm2pgsql is reading my XML. The files are exported from JOSM and containing elements from the API test server (it's working fine with XML files containing elements from the live server).

I've tried to find which XML elements was causing crashes and at the end I can see that even an very  basic XML content causes a crash :

<?xml version='1.0' encoding='UTF-8'?>
<osm version='0.6' upload='true' generator='JOSM'>
  <node id='4298138009' visible='true' version='1' changeset='56614' lat='48.8437993' lon='2.3729329' />
  <node id='4298138026' visible='true' version='1' changeset='56614' lat='48.844187' lon='2.3723893' />
  <way id='4296639452' visible='true' version='1' changeset='56614'>
    <nd ref='4298138009' />
    <nd ref='4298138026' />
  </way>
</osm>

If I remove the <way> element there's no more segfault !

I was testing with the osm2pgsql package from Debian Wheezy (0.80) but I've the same behavior with the latest Git version

Thanks for the help, Vincent.
