Sorry for my lack of response -- I was waiting for the kMSan instance
to sync, but it is currently down, and has been down for four days and
a half now.

The kMSan instance got the time to run 24h before it broke for unrelated
reasons. 24h before your patch, it triggered the bug 6 times. 24h after
your patch, it triggered the bug 0 times.

So indeed, we can call it fixed, thanks for the fix
