Subject: bug#40317: 27.0.90; Reverting a buffer that visits C file signals an error
Date: Sun, 29 Mar 2020 16:26:33 +0300 [thread overview]
Message-ID: <83k1335m2e.fsf@gnu.org> (raw)
When I visit a C source file that already has a buffer that visits it,
and that file has been changed behind Emacs's back by "git pull",
Emacs frequently signals an error. Here's an example:
Debugger entered--Lisp error: (args-out-of-range #<buffer xfaces.c> 1 217135)
parse-partial-sexp(1 217135 nil nil nil syntax-table)
c-after-change-mark-abnormal-strings(214738 215088 0)
#f(compiled-function (fn) #<bytecode -0x1ffffffff8fc4c10>)(c-after-change-mark-abnormal-strings)
mapc(#f(compiled-function (fn) #<bytecode -0x1ffffffff8fc4c10>) (c-depropertize-new-text c-after-change-escape-NL-in-string c-parse-quotes-after-change c-after-change-mark-abnormal-strings c-extend-font-lock-region-for-macros c-neutralize-syntax-in-CPP c-change-expand-fl-region))
c-after-change(214738 215088 0)
insert-file-contents("branch/src/xfaces.c" t nil nil t)
revert-buffer-insert-file-contents--default-function("branch/src/xfaces.c" nil)
revert-buffer--default(t t)
revert-buffer(t t)
find-file-noselect("branch/src/xfaces.c" nil nil t)
find-file("branch/src/xfaces.c" t)
funcall-interactively(find-file "branch/src/xfaces.c" t)
call-interactively(find-file nil nil)
command-execute(find-file)
In this particular case, the buffer's point-max is 216784, which
explains the error, but I have no idea where did the 217135 value come
from, because AFAICT the latest change in Git (the emacs-27 branch)
made that file larger, not smaller.
I hope this can be fixed soon, as this happens quite a lot to me, and
is very annoying.
