How will this interact with preallocated exceptions (e.g. from
Liran's dconf
talk last year)?
It will copy them and throw the copy.
Copy means allocate and then deallocate in the catch, defeating the
whole propose of preallocating. Would it be possible to just set a bit
somewhere that indicates that the exception is preallocated and need not
be freed.
So for instance:
throw new Exception; // this is allocated exception
auto e = makeMeAnException();
throw e; // this is preallocated exception (need not be freed in the catch)
