Subject: | bug#57804: An infinite loop in a `fontify-region' function causes Emacs to hang indefinitely |

E.g. in my case this happened in Logview mode, because it expected `widen' to, well, widen, but Emacs `master' introduced half-cooked narrowed locking that broke that expectation
Yes, master contains work in progress. If you want stable code, you should use the release branch.
Note that the "fully cooked" narrowing will not magically solve that problem, though. Logview will have to be adapted to deal with the possibility of a locked narrowing. What you should most probably do in your case is to increase the value of long-line-threshold (or disable whatever causes Logview to infloop when locked narrowing is in effect, if that's feasible).
