I would think that it would be sufficient to either limit the 
size of an exception and provide a fixed size buffer in 
thread-local-storage (256 bytes).

Yes, that means giving up throwing "strings" and retaining old 
exceptions, but I think that is acceptable for system level 
programming.

I think LWDR also tries to solve this.
Maybe a similar approach could be used.

This? https://github.com/hmmdyl/LWDR

Hm, looks like they add a lot of stuff, but some of it seems to 
be opt-in.

Their plan says they have a working implementation for GDC, but 
not LDC:

Ok, let's see what they come up with. The ideal would be to reuse 
whatever C++ does.

Each compiler does its own way, and on Visual C++'s case it takes 
advantage that Windows supports exceptions at the OS level.

betterC doesn't need exception

why do you want that? use error codes

if that's not enough, let's think about something better than 
exception
