Writing Multithreaded Exception-Safe Code

Question

What are the tensions between multithreading and exception-safety in C++? Are there good guidelines to follow? Does a thread terminate because of an uncaught exception?

Answer 1

C++0x will have Language Support for Transporting Exceptions between Threads so that when a worker thread throws an exception the spawning thread can catch or rethrow it.

From the proposal:

namespace std {

    typedef unspecified exception_ptr;

    exception_ptr current_exception();
    void rethrow_exception( exception_ptr p );

    template< class E > exception_ptr copy_exception( E e );
}
