Subject: Sudden jumping point in buffer. Probably a bug?
Date: Wed, 18 Nov 2015 19:35:55 +0100 [thread overview]
Message-ID: <20151118183555.GI5776@scotty.home> (raw)
Hello,
I'm using emacs as 64 bit compiled on windows 7/64 and linux 64 bit. Since
quite a while I have the problem that, while typing, the cursor (point) is
sometimes suddenly jumping to another position in buffer.
First I thought I have touched the touchpad of my laptop. But this also
happened without touchpad on normal keyboard.
I also thought first it just happens on windows. But I saw it a few times on
linux too.
I'm not sure but perhaps it also happens not just in C++ but also in
Org-mode.
My guess that it has something to do with fontifying (semantic?). With this
I have gone through the commits of emacs and saw that at May 4 2015 there
was a change with save-excursion and a new function save-mark-and excursion;
but I haven't seen a bug in implementation at first sight.
Alas I don't know the version of my (older) emacs which haven't had this problem.
(Because of this I now compile the git commit signature into the flags like:
./configure --with-x ... CFLAGS="-g3 -O3" GIT_VERSION="$(git describe)"
With this I have tha signature available in system-configuration-options.)
I even don't have a clue how to produce this. So for the moment I'm doing
ghost bug hunting... :-(
Anybody else having this problem?
Any hint how to dig into the problem? (view-lossage does not show any
unusual)
With kind regards,
Stefan
