OK. But we have valid Ada testcases exhibiting the problem.

Right, but the problem doesn't trigger, probably because of the relative
encoding:
.LLSDACSE3:
.byte 0x1
.byte 0x0
.align 4
.long DW.ref._ZTIZ3foovE1S-.

Yes, I think that's the crux of the matter: for the time being, neither the
C++ nor the Ada front-end mangles local exceptions. Either they should or
the problem lies in the EH machinery.
