The basic problem I'm experiencing is that getting an exception_ptr results inherited parameters getting lost when virtual inheritance is used.
The code below demonstrates a simple example. "bar" is lost in the print. Changing derived_except to be:
struct derived_except : base_except { int i; };
will cause the inherited values to be copied into the exception_ptr; however, this has all the standard problems associated that come with not using virtual inheritance.
This looks like a bug to me. The C++11 equivalent behaves has expected and inherited values are maintained in the exception_ptr. Any thoughts?
The only way to make it work is to restructure clone_impl to use the compiler generated copy constructor. In Christ, Steven Watanabe
