First, as you point out, your code can't be deployed even if it was correct, because many compilers don't yet implement std::exception_ptr.
There a couple of possible answers here, but the simplest would be just to say that you'd need to implement the standard functions for this compiler. I cursory look at the microsoft documentation suggests that this would be possible. and not all that difficult.
Secondly, your program erases the type of the exception object. In C++, the type of the exception and not its value corresponds to its semantics.
hmmm looks to me that my program is not losing the type. The highest level catch does catch the original type and just to be sure I used typeid to print the type restored at this level. So the program output is $ ./test_misc caught other exception # display original exception type caught exception_wrapper_base caught my_exception # display exception type at highest level 999 # display attached information.
