That bit about excessive-variable-binding rang a bell; I dimly
remembered seeing a couple of commits increasing max-specpdl-size "not
too long ago".  git-log turned these up:

* 2022-01-31 "Enlarge max-specpdl-size for generation of files in
  .../admin/grammars" (be2566eeab)
* 2022-01-30 "Enlarge max-specpdl-size for generation of leim-list.el in
  bootstrap" (46611aa468)

So here's a "monkey see; monkey do" patch that causes this error to go
away; no idea if it's The Right Thing™ though?
