Actually in my mind the --image and the use of other file types does tell us something. Either I modified DynamicLibrary.cpp to tell us it was going to close a library or it was already there but I did add another notify to tell us when it returned from the close. If I display a gif, jpg, rgb, bmp using osgViewer I will see the appropriate plugin.dll open, see the message it is closing and the message it closed and the program will terminate normally. If I display an osg file (without the --image since it doesn't like that for an osg file) then I get the following output from gdb. I changed the order of the closes because in Cygwin if the cygwin_osgdb_osgd.dll closed first you never saw the close for cygwin_osgdb_rgbd.dll. Changing the order Lifo vs Fifo (not sure from what to what) allowed me to see the close on the rgb and then see it hang on cygwin_osgdb_osgd.dll. Now as I say using the --image and other type images then osgviewer terminates normally.
