What about the Lisp backtrace? And since this is an optimized build,
the backtrace is almost useless anyway. Can you try reproducing this
in an unoptimized build?

This part does look as if Emacs was going to close the X display where
the frame was displayed. Were all other frames in that session on
other displays? If not, how come Emacs is about to delete the
terminal? Here's the relevant code:
if (terminal->reference_count == 0)
{
Lisp_Object tmp;
XSETTERMINAL (tmp, terminal);
kb = NULL;
Fdelete_terminal (tmp, NILP (force) ? Qt : force);
}
Can you look at the value of terminal->reference_count?
