Puntif Report post Posted February 3, 2007 (edited) I'm running Linux (slackware 9.0.0). I was in Idaloran and clicked on the Palon Vertas banner when I got a seg fault. I compiled this client from CVS on Jan 8. Program received signal SIGSEGV, Segmentation fault.

Puntif Report post Posted March 10, 2007 I don't see any CVS changes to bbox_tree.c except for the eye candy one so I guess nobody has addressed this. This crash happened again today. It happened on a map transition - I had clicked on the boat banner in VOTD to go to DP. This time I got a little more info from gdb. Program received signal SIGSEGV, Segmentation fault.
