That crash looks pretty inexplicable. The pointers are all valid, the indices are all within range... Meh. Retitling as an expected SIGSEGV is unexpected. Created attachment 59670 [details]
captured backtrace 2
I just hit another SIGSEGV, which although not quite identical might be related as it also passes through tor_inplace: tor_inplace() calling fill_buckets() (please see attachment).
This happened as I was watching some youtube videos, just as I clicked on the youtube searchbar.
Intel driver is/was at commit b790ba2ec9ead51227d85fc8630bc7505eb7d7b3 .
That segfault is still collateral damage.

Created attachment 59517 [details] captured backtrace While working with eog ('the eye of gnome') suddenly X crashed. The crash appeared to happen at the exact moment of a click of the main eog-window, however I've been clicking that window for some time before and after the crash without adverse effects. I've attached the backtrace that was captured.
