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

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

Once it in the luatex trunk, I will check it right away.
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.

It does also depend on the width of the text because when I use 48pt in the
example below
the height of the brace is always the same but with 49pt the height increases
after the first page.
An experiment:
width = 48.0719985pt
height = 4.968pt (constant)
width = 48.0719986pt

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
