Thanks -- I'd forgotten about that and just tried it. If you are
looking for pixel-level changes, my script makes it easier to see
exactly what the changes are. On the other hand, diffpdf is more
polished than my script.

Is this change still also needed (in addition to the luatex fix)?

I just compiled and installed luatex 0.79.1 r5033, remade the formats,
and the result passes my underbrace tests (the 30,000 iterations and the
examples in my book mss).
Thank you for the great debugging.

I thought the problem might lie with the general
\definemathunderextensible (math-stc.mkvi), because underbrace is
defined as

["023DF]
Other underextensibles include \underbar:

Dear list,
As I copyedited my book, I noticed examples where the underbraces in
math formulas were not aligned vertically, especially toward the end of
the book. Eventually I realized it was not due to my growing
copyediting skill, and I have made the following minimal example showing
the problem
