boost::shared_ptr weirdness

[Paul Davis <pjdavis engineering uiowa edu>]

Has anyone ever noticed weird behavior with boost::shared_ptrs and 
widgets?  I've been getting some random segfaults when closing my 
programs.  They seem to be coming from removing a container that 
contains a widget that is a member of an object referenced by a 
shared_ptr.  I think.  I haven't gotten it to be reproducible.  I'm just 
using this as a shot in the dark to see if there are documented no-no's 
for using boost's shared pointers or something.

Thanks,
Paul
