Emacs hangs worse than usual lately

[joakim]

I have used a workaround for a couple of years because my emacs hangs
when changing network interfaces:

#/bin/sh
`lsof -n|grep emacs|grep nntp|sed "s/.*TCP\ \\([^:]*\\):.*->\\([^:].*\\):.*/  
export a=\\1 export b=\\2/"`
echo $a $b
ifconfig lo:1 $a
ifconfig lo:2 $b
echo press enter when emacs is alive
read
ifconfig lo:1 down
ifconfig lo:2 down

Anyway. This has lately failed to bring me joy.

It would be nice to address the root issue but I'm not sure what that is
anymore.

The gdb backtrace is attached and it look similar to what it usually
looks like.

Is there some way to know the corresponding lisp code?
