Re: [PlayerStage-Gazebo] SVN Gazebo install

[<sa...@co...>]

Dear Nate:
   I just tried gazebo svn version 170 and I am still experiencing problems (but at least they are slightly different).  I think there might be either a bad pointer or a corrupt stack somewhere because gazebo always segfaults under gdb (bt is attached below) and without gdb, gazebo sometimes segfaults and sometimes does not.  When gazebo segfaults in gdb, I get a gray band on the top of the window and on the right side (where the toolbar and info panel should be).  Without gdb, if gazebo does not crash I can get a File menu in the toolbar and a xyz/rpy readout in the info panel but the main window is still all black.  Also, I can still generate jpgs that have those same strange images in them. When gazebo crashes, I get:
