So how come Emacs gets a SIGHUP? This is the crucial detail that is
missing here. Basically, if SIGHUP is delivered to Emacs, Emacs is
supposed to die a violent death.

Wait, you mean the crash is during exiting Emacs? That could mean
Emacs receives some input event when it's half-way through the
shutdown process, and the input descriptor is already closed.
But the backtrace you posted shows SIGHUP during GC, which is AFAIU a
very different case.
