Nodelets: pure virtual method called, process died (-6)

edit

I get the error in the question title everytime one of my Nodelet classes calls ros::requestShutdown(). I've tried debugging it in gdb, but besides the fact that the stacktrace is 5 pages (!) long, it doesn't tell me much, apart from a lot of references to boost::shared_ptr and checked_delete.

Is calling ros::requestShutdown() from a Nodelet unsupported or is this a bug somewhere?

Problem is the crash is causing my Nodelet destructors to not be called, which makes it hard to do proper cleanup of resources.

Breaking using ctrl+c does cleanly shutdown everything and calls destructors.

Edit: @Lorenz, you're right, I should've included more info.

System: Ubuntu Lucid (10.04.3), ROS Electric from debs.

The class that calls ros::requestShutdown() does so in a callback, whether that callback is called by a subscription or as a service doesn't matter.

On second thought it seems like the Bond dtor (frame 10) tries to stop/delete some timer (frame 9) which seems to try to use the ros::TimerManager (frame 7) which might have already been stopped/destructed.

Stacktrace:
