Category: stage Group: trunk Status: Open Resolution: None Priority: 5 Private: No Submitted By: Daniel Dube (daniel46) Assigned to: Richard Vaughan (rtv) Summary: Stage segmentation fault on unsubscribing interfaces Initial Comment: Stage crashes every time I unsubscribe an interface. Neither the type of the interface nor the type of the client seems to influence this behavior. This bug can be reproduced by starting player with the worlds/simple.cfg configuration of stage. Now subscribe and then unsubscribe an interface. This causes a segmentation fault of the stage module on my system. I'm using an Ubuntu 9.10. I reproduced this problem with stage version 3.2.2 and revision 8014. I also tested playerv, c++ and c player clients.
