I was actually looking at the issue to the test was quick, yes the
error disappears with the -noreset option. Seems that stopping the
server is the problem. The log was saying that swrast was missing so I
added but it didn't remove the error. The last message before the
crash is:
[3551284.259] (II) VIVANTE(0): Setting screen physical size to 338 x 211
[3551284.297] (EE)
[3551284.297] (EE) Backtrace:
[3551284.297] (EE)
[3551284.297] (EE) Segmentation fault at address 0x76fd10dc

On the swrast topic, should we add to as a select in the Config.in as
it seems to the be case in Yocto?

Also tried updating to latest graphics xdriver and vivante libs which
are meant for 3.14 kernels but I confirm this is also working on
3.10.53. But it didn't help though, I'll wait for next cycle to switch
packages to their 3.14 versions.

To reproduce the issue, I tried the vivante tutorial7 as well as
xterm, both crashed the server when closed although sometimes closing
xterm was ok (weird I know).
