Andrey Semashev:
Sorry to reiterate, but I think this issue is rather critical and it would be very nice to have it solved in the upcoming release.
Peter, have you reviewed the patch I attached?
Yes, I have reviewed your patch. I don't want to merge the current shared_ptr, on which your patch depends. (Not at this time, at least). I also think that your patch stands to be improved a bit, but obviously, this is of secondary concern. (In addition, I prefer to add tests that identify the failure either before, or in concert with, commiting a fix.) If this issue is considered important enough to block the release, I'll see what I can do to unblock it. But keep in mind that (a) make_shared is still undocumented and (b) the release branch throws bad_weak_ptr instead of silently doing Bad Things.
