bug#47244: 28.0.50; SIGSEGV in long-runnning Emacs

[Michael Welsh Duggan]

I have managed to catch a SEGFAULT in a long-running Emacs in the
debugger.  I've been unable to recreate this SEGFAULT on demand, but it
seems to be happening when I am attempting to "reset" gnus after
switching my work VPN on/off.  I will keep the gdb session up an running
in case there is some more that can be done with this.
