Reverting 07da629 does appear to prevent the crash.  Specifically, as a
sanity check, before reverting, I ran my build from master under GDB
again, started Gnus, but now Emacs didn't crash; however, then I
composed a mail to myself in Gnus and upon sending it, Emacs did crash
exactly as before in fchmodat.  This I did `git revert -n
07da629926daf849aab248175c88cf53a5e21558', rebuilt, started Emacs again,
started Gnus, there was no crash, sent a mail to myself, again with no
crash, and pulled the mail into Gnus also without the crash.  So it
appears that that commit is indeed the cause of the crash.  Thanks for
pinpointing it.
