Re: problem on using shared_ptr

It's strange that you can not catch the exception.  That line (1156) is
the end of the method in the object class that does the call to lua, so
perhaps if you use your debugger to step line by line from "pu(sender)"
onwards.  Does it print "update" ? or not get that far?

That's what I would do.  Then if you have no luck, perhaps try with
ordinary raw pointers, and see what changes.

In your Lua script, do you have "print" or "prient" like you have in
your email?
