Can you make it fail over and over once it starts failing?
Typically I can't make it work again after that point at all. At
least, not consistently.
There is a misunderstanding here. The question is NOT whether you can
"make it work again"--that goal is irrelevant--but whether (once in
that situation) you can make it fail.
When you get in a situation where a certain operation reliably fails,
you can try to observe why.
If the problem starts up again and I have an image in which edebug has
failed in the manner I've described, perhaps there are investigations
I can run on that image?
I don't know what you mean by "image" here.
When you have an Emacs process in which edebug reliably fails when you
do a certain thing, you can try inserting (debug) in various places in
code in edebug.el that ought to run when you do the thing that fails,
then do that certain thing, and see where control gets to and where it
does not get to. You can also look at values of variables inside
edebug this way.
With some luck, you'll figure out the bug.
This will require learning something about how edebug.el works.
You must not set yourself the goal of avoiding learning that.
