The only change compared to your original should be that I load tm.el, activate tm-menu-mode, and use M-g <n> key bindings instead of C-l and so on. With this, emacs -Q, I - open tty-1, tty-2, tty-3 in that order - then I click in the yellow frame - click on the Buffer menu in the menu-bar - click on *Messages*. Effect is a bit strange, some complaints about mouse bindings in the root frame, but no assertion. So I guess I'm missing something important. Any ideas?

Not really: I do the same but positioned the yellow frame more to the
left so that it is not obscured by the other two child frames. Both
tty-child-frames.el ("/home/martin/temp/tm.el" is my location of your
tm.el) and my patch are attached. I also attach a screenshot
immediately before clicking on the Buffer menu. A complete transcript
of the debugging session is below.
This is with master after

So, I think I have now exactly what you are using, and I eventually
got a segfault somehow, and found out something:
The root frame ended up containing glyphs from a dead menu frame. The
dead frame's face cache was set to NULL because it had been freed. The
series of events leading to this is still unclear to me. At least we
never copy glyphs from a dead frame, that much I can say.
Doesn't look like the assertion you are seeing, but maybe it's somehow
related.
More in the next round.

Should deleting a frame on a TTY make sure there are no glyphs in the root frame's current glyph matrix whose frame pointer refers to the frame being deleted?

It should. Deleting a child frame should ensure that its root is redrawn thoroughly, for the long longer existing child. Which would include clearing the root's current matrix. Why that doesn't happen is unclear to me.
