The specific org file doesn't matter. The window size doesn't matter. This crash happens to me occasionally (2-3 times a week), always on an org file, always on mwheel-up (which invokes mwheel-scroll). Eli, can you tell something from the backtrace here? http://lists.gnu.org/archive/html/emacs-orgmode/2014-06/txtkIBvnmHi_F.txt The critical lines are: die at C:\msys\home\Dani\emacs\build\src/../../emacs-24.3.91/src/alloc.c:6826 pop_it at C:\msys\home\Dani\emacs\build\src/../../emacs-24.3.91/src/xdisp.c:6060 set_iterator_to_next at C:\msys\home\Dani\emacs\build\src/../../emacs-24.3.91/src/xdisp.c:7523 move_it_in_display_line_to at C:\msys\home\Dani\emacs\build\src/../../emacs-24.3.91/src/xdisp.c:8838 > > ../../emacs-24.3.91/src/xdisp.c:6066: Emacs fatal error: assertion failed: > > (BUFFERP (it->object) && IT_CHARPOS (*it) == it- > >bidi_it.charpos && IT_BYTEPOS (*it) == it->bidi_it.bytepos) || (STRINGP > >(it->object) && IT_STRING_CHARPOS (*it) == it- > >bidi_it.charpos && IT_STRING_BYTEPOS (*it) == it->bidi_it.bytepos) || (CONSP > >(it->object) && it->method == > GET_FROM_STRETCH) The code can be seen here: https://github.com/mirrors/emacs/blob/master/src/xdisp.c#L6127 > This is an assertion violation, not a crash. The failing assertion causes a crash, so I'm not sure what's the difference. Is there an emacs build that doesn't crash on eassert() failure? > Some assumption in the > code turned out to be false, but it is not possible to know which one, > and whether it's just a wrong assumption or a real problem. It seems the assertion does basic consistency checks of the IT structure. What is it->bidi_p? I don't use BIDI text: this happens on ascii org files. I guess I'll upgrade Emacs and Org and hope for the best...
