Dear Maintainers, readers ...

While updating the solidrun cubox (dove) running debian from 5.6 to 5.7 I came across a new crash in etnaviv that did not occur before - and is also present in 5.8.0:

Since I understand neither the crash nor the patch that triggers it, I am posting this here in front of more trained eyes ;)

Good news it is already fixed, but patch is not upstream. Could you try this patch and report back, especilly if the patch does not help.
