I think that's a possibility. On __APPLE__ we will never be in a situation where gcc's runtime will be in play at the same time as libc++abi (so that possibility has not been designed for). So this is more of a question for those interested in libc++abi running on non-Apple platforms. Is this a scenario people want to tackle? To work it will take some considerable design. I can think of two ways to go: 1. Try to mimic gcc's runtime in every way, and somehow make it ok for either run time to catch an exception thrown by the other. 2. Have distinct exception_class ID's, to give each run time a chance to recognize that they are dealing with a foreign exception and take suitable action. I have not given the problem enough thought to have formed an opinion, and probably won't until I complete the personality routine.
