    Please add this fix to 5.6.

    How come is this fixed when 2017.1 is not ready, and there is no backport of the fix for 5.6? Or should we create a new issue for a 5.6 backport of this to be able to vote on that?

    Is the recommended solution to use 2017.1 for webassembly builds now?

    I'll continue solving with 5.6 by making sure we don't let unhanled exceptions thru in the application code, which is of course good anyway, but hard to ensure especially with networking involved.
