I didn't manage to reproduce this issue yet, but it seems that
Emacs 26.2 can get stuck in an infinite loop in garbage collection:

Lisp Backtrace:
"Automatic GC" (0x0)
"vector" (0x3b9fbbb8)
"internal-echo-keystrokes-prefix" (0x3b9fbdd0)

In this situation, Emacs never leaves mark_kboards.  The variables here
are:

(gdb) p &kbd_buffer
$7 = (union buffered_input_event (*)[4096]) 0x9a23e0 <kbd_buffer>
(gdb) p ((union buffered_input_event*)kbd_buffer + 4096)
$9 = (union buffered_input_event *) 0x9da3e0 <input_was_pending>
(gdb) p kbd_fetch_ptr
$4 = (union buffered_input_event *) 0x9d9340 <kbd_buffer+225120>
(gdb) p kbd_store_ptr
$5 = (union buffered_input_event * volatile) 0x9a23e0 <kbd_buffer>
(gdb) p event
$6 = (union buffered_input_event *) 0x9ad078 <kbd_buffer+44184>


The loop starts with

    for (event = kbd_fetch_ptr; event != kbd_store_ptr; event++)
      {
        if (event == kbd_buffer + KBD_BUFFER_SIZE)
          event = kbd_buffer;

This seems suspicious given that kbd_fetch_ptr > kbd_store_ptr.  It
seems like this loop can never terminate, but I don't know how we got
into that situation.

I installed the first attached patch into Emacs master and am marking this bug as done. I am not sure whether a simpler patch should be installed into the emacs-26 branch, but the second attached patch should do the trick for that if needed, not that it's easy to test this sort of thing.
