1 year ago EWG supports:
-users verifying that this model meets their needs, particularly for pointer zap -authors work with SG22 and WG14 to align C and C++ solutions -implementation experience be obtained -usage experience be obtained
then we want to see the paper again

1 year ago The link looks fine, the paper just hasn't yet been published where the wg21 link bot can find it.

6 months ago @NinaRanns: Should this issue get an update from the SG22 discussion?

commented
6 months ago probably :) SG22 had a meeting to discuss the issue. WG14 felt the wording presented in P2434 doesn't solve the problem from WG14 perspective. The room didn't find a common way forward. Notes from the meeting can be found here

Not consensus (too many neutrals).
P2434R1 Nondeterministic pointer provenance: forward to SG1/CWG/LEWG for inclusion in C++26.

3 months ago SG1 believes that the approach of P2434R1 can address the zap problem with some additional (simpler) changes e.g.:
