[SOLVED]emacs segfault

Hello,

I have a problem on my fresh arch install on my Desktop
when I exit emacs, I got a segfault. I have install kde plasma and only nvidia driver with nividia-ligl (no xf86-video-intel)

I try to install intel-ucode, here is my boot tree:

Re: [SOLVED]emacs segfault

Are you fully up-to-date?  There was an issue solved in nvidia 358.16.

Re: [SOLVED]emacs segfault

yes, the full system is up to date with 358.16

Edit: when I run nvidia-settings, and quit it from the GUI it segfault too

Edit2: others apps seem to segfault as well in fact, when I run firefox from command line, it display segFault but the window still works. I do not understand.

Edit 3 : So after some researches I think I have this bug https://bugs.archlinux.org/task/46064?project=1
and in the description of beta driver 361.18 we can read :

Fixed a bug in the EGL driver where a mutex was unlocked more than once. This triggers undefined behavior, and in particular, if lock elision is enabled in glibc, may result in a segmentation fault.

this is why I get segfault on many programs.

I read from the wiki that install driver from the official website is not recommanded. Has anyone tried it ?

Re: [SOLVED]emacs segfault

Ah - I assumed it was fixed in the .16 version.   .18 is in [testing] but requires updating to the testing kernel too...
