Full log
Message #14 received at 7348 <at> debbugs.gnu.org (full text, mbox):
Some timing has changed. I got a crash because of BadCursor. It only happens
if you start Emacs and put the mouse fast within the frame on a non-toolkit
build. Initializing cursor to No_Cursor in note_mode_line_or_margin_highlight
fixed tha.
