I'm pretty sure there's a reason Austin used lexical-let in the first
place, but maybe someone can convince me it isn't needed.

Since emacs 26 is not released yet, I guess you mean the master branch
of emacs? Since it currently doesn't compile, I can't really debug. Do
you have a precise revision that you have tested?

If you want to try to debug this you could try using git bisect (on
emacs) to figure out what commit broke things.

Another useful thing to know is whether emacs master can byte-compile
the minimal example attached. There will be warnings, but there should
not be any errors.

PS: I couldn't actually apply that patch. Maybe try git-format-patch and
use an attachment if using gmail.
