seems like a compiler bug… did you update it recently?

I regularly update from ubuntu 20.04

well, as I wrote above you get a crash inside the compiler, and the message suggests to report it as a bug to the gcc devs…
for ART, did you try recompiling from scratch?

Yes I tried to download it again, but failed at the same point.

Booting the machine again seems to resolve the problem. The compilation resumed at the break point.
