I did.  I've inverted the order of those words many times, and I didn't
catch it this time.

Before that, I include the backtrace with your latest patch.  And here's
the interesting bit:

(gdb) p Vwindow_list
$2 = XIL(0x55555863cae3)
(gdb) xlist
$3 = 0x555556fc8af5
Lisp_Vectorlike
PVEC_WINDOW
$4 = (struct window *) 0x555556fc8af0
84x59+0+0
---
$5 = 0x555556fc8d05
Lisp_Vectorlike
PVEC_WINDOW
$6 = (struct window *) 0x555556fc8d00
84x1+0+59
---
nil
(gdb) p Vwindow_list_2
$7 = XIL(0)

Right before this I hit a breakpoint that that I had set up that, once
again, implied that in this call of window_list() happened subsequent to
a call to window_list() that didn't complete, somehow. 

Before running with block_input(), unblock_input(), I'm going to modify
the sources to set a physical variable to one on entrance to the if
block and set it back to zero at the exit.  At least then I can be sure
that an unintended termination of this function is really happening and
that it is not a debugger artifact.
