   Thank you, this is very helpful. I guess I'm not too surprised
that it works on Solaris 10. Your support of a 20 year old OS is
admirable.

I tried --without-xinput2 with the GTK version, and it does
indeed skirt the problem. I can now reliably run it without
crashing.

Since this all worked with 28.2, I guess that Emacs
started using XInput 2 features in the 29.1 branch?

Unfortunately, with the Lucid version, while --without-xinput2
seems to get past the failure I reported, there's now a different
failure:

    % src/emacs
    X protocol error: BadDrawable (invalid Pixmap or Window parameter) on protocol request 134
    Serial no: 1318
