I can enter text and save the buffer before clicking menu items.  When I
inspect the content of the file with another editor, I see that it
contains the text that I entered before saving.

Given on how rarely I update to the latest development version of Emacs,
I can't say anything more precise than that the problem was introduced
during this summer.  I know, not very helpful.

What do you mean with bisect?  Checkout earlier versions and test them
until I find the bad commit?  Given the high volume of commits in Emacs
this would take quite a while even when using an efficient
search strategy.
