Thanks! I thought by "X11 session crashes" you meant the Emacs session. If X11 itself crashes, then I'd first look in the syslog file for any more detailed information about the crash, and then look for description of similar X11 crashes on the Internet. Also, perhaps upgrading or downgrading your X11 version would fix the problem. Perhaps you can run X11 itself under GDB, but I don't know how. Sorry. One other idea is to change the font you use for the default face, maybe it's the font which causes the problem. Cairo could also be the culprit, so using a different version of Cairo or a non-Cairo build might solve the problem. Finally, can I ask why you need to repeatedly press C-= so many times? is that a real-life need or just a curiosity?
