Ah, right, that one is something else, so let's not add those last
Reported-by/Closes.

However, that crash was bisected to the same guilty patch, so the
issue is somehow related. Even if we were to mark it as to be fixed
with the patch I sent, this wouldn't be critical: syzbot would just
rereport it, and with fresher stack traces.

Thank you!
