I now run with this patch and I only had one crash in a couple of days.
But this was a crash in the garbage collector, quite different from what I
used to have.

However now I have occasional hangs in select(), always when using gnus.
It could be a server that is not responding, but I am not sure. I attach a
stack trace below. The hang doesn't get broken with C-g (the well-known
problem), but sometimes it helps to Ctrl-Z gdb (I am running emacs from
gdb), and/or hitting Ctrl-C in the gdb terminal window. Continuing then
resumes normal life but it can take quite some time.

Program received signal SIGTSTP, Stopped (user).
