Yes, it may be. Thanks for reporting it.

Two  weeks ago, I was building a qemuarm64 image on my laptop
(i7, 16 GB, SSD running Ubuntu-16.04)
and I saw a similarity bizarre result from running a build
in that chrome and then the X server were both killed.
I wasn't in front of the system when this happened so
I can't say exactly what was going on.

I did collect some of the logs from my IRC client and chrome:


[423679.028437] konversation[23416]: segfault at 7f72d2c33ce0 ip 
00007f72eca4e818 sp 00007ffc7f450ae0 error 4 in

00007ffd26c25af0 error 4 in libX11.so.6.3.0[7f63f75ed000+135000]


and then from the X server:

Aug 29 16:11:59 laptop org.a11y.atspi.Registry[4763]: XIO:  fatal IO 
error 11 (Resource temporarily unavailable) on X server ":0"

libX11.so.6.3.0[7f63f75ed000+135000]



In my case, I had added meta-oe to oe-core and was building:
    MACHINE=qemuarm64 bitbake imagemagick

I reproduced it once in X then did NOT see it happen when
I built with an X session running but building on the console.
i.e. the build of imagemagick for qemuarm64 succeeded.

I've removed the build logs it seems but I'll see if I can reproduce
the failure overnight.
