I noticed that Cuirass seems to have lost track of this build:

https://ci.guix.gnu.org/build/1565808/details

The duration is currently 33246 seconds, and continues to increase.

However, the log file ends like this:

------
@ build-succeeded /gnu/store/h9l2j1c7p7q5y9ds77f54ymfq64hqv0c-libaom-3.2.0.drv -
------

I've attached the log file, compressed with XZ.
