Description Francisco Lopes 2014-03-12 19:38:01 UTC 
I'm using xorg-edgers PPA and recently on Ubuntu 13.10 and while I edit in GVim 7.4.131 the Xorg Server is crashing and I go to Logon screen.

I've noticed this is happening when I'm in Vim Insert mode and I click CAPS-LOCK which here is mapped to ESC key. Just upon releasing it crashes all the time. Console Vim doesn't suffer from same problem.
Comment 1 Francisco Lopes 2014-03-12 19:38:47 UTC 
I'm with latest PPA updates
Comment 2 Francisco Lopes 2014-03-12 19:40:54 UTC 
Sorry, better description is that I'm coding some C file, and the crash happens after I enter the ; character, and then, go to normal mode with ESC.
Comment 3 Francisco Lopes 2014-03-12 19:51:55 UTC 
Better description, the plugin https://github.com/Valloric/YouCompleteMe must also be installed...

I've noticed that disabling this plugin Xorg doesn't crash.

With that plugin, editing a C file, declaring a variable, pressing ; and then ESC twice ocasionates the crash.
Comment 4 Michel Dänzer 2014-03-13 03:12:09 UTC 
Please attach the Xorg.0.log file and, if possible, a gdb backtrace corresponding to the crash.

There's no symbolic stackdump, so please try:

addr2line -i -e /usr/lib/xorg/modules/drivers/intel_drv.so 0xcbfb6

but it looks just like irregular memory corruption.

    sna: Nullify extra fill.ops
    
    I forgot that the initial memset(&fill, 0, sizeof(fill)) was no longer
    performed and we rely on explicit initialisation during the setup, so
    add the missing fields.

Thank you, PPA was updated today and GVim stopped crashing the machine.
