It seems to have returned in some way. I can't reproduce this on Emacs
26, but on latest master, the following steps:
0. emacs -Q
1. (progn (setq debug-on-error t)
(setq jit-lock-stealth-nice nil)
(setq jit-lock-stealth-time 0)
(find-function #'next-property-change))
2. C-x C-e
almost immediately lead to the following backtrace:
Debugger entered--Lisp error: (error "Invalid search bound (wrong side of point)")
search-forward-regexp("\\<\\(\\(?:enum\\)\\)\\>[^][{};/#=]*{" 1673 t)
c-font-lock-enum-body(1673)
font-lock-fontify-keywords-region(1123 1673 nil)
font-lock-default-fontify-region(1123 1673 nil)
c-font-lock-fontify-region(1173 1673 nil)
font-lock-fontify-region(1173 1673)
#f(compiled-function (fun) #<bytecode 0x1565bb8a9581>)(font-lock-fontify-region)
run-hook-wrapped(#f(compiled-function (fun) #<bytecode 0x1565bb8a9581>) font-lock-fontify-region)
jit-lock--run-functions(1173 1673)
jit-lock-fontify-now(1173 1673)
jit-lock-stealth-fontify(t)
apply(jit-lock-stealth-fontify t)
timer-event-handler([t 0 0 974323 nil jit-lock-stealth-fontify (t) idle 261000])
I'm not sure if this says anything, but when the *Backtrace* buffer is
displayed, the textprop.c buffer is marked as modified. Could this be
related to the before/after change machinery?
A similar error I occasionally see, but have not yet figured out how to
reproduce:
Error during redisplay: (jit-lock-function 19569)
signaled (error "Invalid search bound (wrong side of point)")
Thanks,
