Segfault on async lookup #29

Closed Niek closed 11 years ago

Niek commented 12 years ago

I upgraded to the latest node version, and now the geoip async lookup calls cause a segfault. Here is some sample code:

var geoip     = require('geoip');
var country = new geoip.Country('./geoip.dat');
country.lookup('127.0.0.1', function(err, country_obj) {
  if(err) throw err;
  console.log(country_obj);
});

Running this results in:

$ node testcase.js 
Segmentation fault
$ node -v
v0.6.7
$ npm ls | grep geoip
├── geoip@0.4.5

The lookupSync calls still work as expected. I'm using GeoIP-1.4.8 by the way.

kuno commented 12 years ago

This script works normally on my machine, with geoip 1.4.8

  /tmp/testcase.js:4
  if(err) throw err;
            ^
  Error: Data not found
  →  node -v
  v0.6.7

This seems more likely an issue of your libgeoip package...

Niek commented 12 years ago

I have upgraded to node v0.6.8, but the issue remains. Tried re-building GeoIP 1.4.8, removing and re-installing the modules with npm... still crashes. Here is the output of strace, hopefully it helps:
