Igor,
I've got 0.8.48 installed, and the dma_code and area_code are working well. however, when I include $geoip_region_name via:
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_REGION_NAME $geoip_region_name;
fastcgi_param GEOIP_CITY $geoip_city;
fastcgi_param GEOIP_DMA_CODE $geoip_dma_code;
fastcgi_param GEOIP_AREA_CODE $geoip_area_code;
My nginx workers start to segfault:
2010/08/03 13:03:51 [alert] 16637#0: worker process 16733 exited on signal 11
2010/08/03 13:03:52 [alert] 16637#0: worker process 16734 exited on signal 11
2010/08/03 13:03:54 [alert] 16637#0: worker process 16732 exited on signal 11
The second I comment out that parameter and HUP nginx, it goes back to working as usual.
