could this just call cxa_throw?

Probably yes, but cxa_throw takes three parameters and I'm not familiar enough with emscripten to know how to extract the relevant values from ex.

seems like you can call cxa_throw(ex, null, null).

Oh I was expecting to get away with it without a test :-/ |

Sorry, yeah, we do need tests for stuff like this, or else we have no guarantee it won't break. Let me know if you need any help writing one. |

Might as well add a test later when things are further along. Merged. |

Just a basic implementation to make Rust happy.
This is the code I used to pass the tests. It's obviously not clean, but it's still better than aborting.
If I have some time I'll try figure out correctly how exceptions handling works in C++ and emscripten and write some correct code.
