--- Comment #14 from Jakub Jelinek <jakub at gcc dot> ---
For the in-place transformation in libsupc++ if something catches the old
failure and a new failure is thrown, is it possible?  The other way around, if
we would be throwing the new failure and catching the old one, doesn't seem to
be possible, the cxx11 failure is bigger (32 bytes compared to 16 bytes for the
old one).  Could we just move it to a temporary, in-place construct the old one
and destruct the temporary?  What if the code then rethrows it and is caught
again in code that expects the new failure?
