I don't think Danny every claimed that 4.3 solved the foreign frame 
problem that Dwarf2 EH suffers from.  I know there was *supposed* to be 
a SoC project to fix that (and another, related one? to add SEH support) 
but I've seen no results from it (either one).

Can you show me where this problem got fixed, in 4.3?  I'd love to be
