…nGH-9059) Address a C undefined behavior signed integer overflow issue in set object table resizing. Our -fwrapv compiler flag and practical reasons why sets are unlikely to get this large should mean this was never an issue but it was incorrect code that generates code analysis warnings. <!-- issue-number: [bpo-1621](https://www.bugs.python.org/issue1621) --> https://bugs.python.org/issue1621 <!-- /issue-number --> (cherry picked from commit 6c7d67c) Co-authored-by: Sergey Fedoseev <[email protected]>

@sir-sigurd: Status check is done, and it's a success ✅ . |
|
@gpshead Is this ready to merge for 3.7? |
|
Yes, though I'd wait until after you do the 3.7.1 release. No need for this to go in during an rc. |
|
This backport is sitting for weeks. It has been properly validated by our buildbot fleet (on the master branch) and everything is fine. So I'm confident that it's safe for Python 3.7. I just merged the 3.6 backport as well. |
