@colesbury Do you know a better way to return an exception reference from an exception ptr? I copied the approach from the existing code, but it seems a bit odd to have to rethrow in order to grab a reference. |

The MPI async work class returned a temporary as reference, which is invalid (hat tip to @sgross for noticing it). This change fixes that and uses a std::exception_ptr to hold on to the exception if applicable, and then returns the reference by throwing it and returning it, like the existing code path.
