Comment 1 Randy MacLeod 2021-06-17 14:48:28 UTC 
Appears to only happen only tumbleweed and likely reproducible.
Comment 3 Ross Burton 2021-06-18 09:26:35 UTC 
Got a patch, it's due to GCC11 being used.
Comment 4 Ross Burton 2021-06-18 14:20:01 UTC 
Fixed in meta-arm master 14b2b0b7cd1bc6e3c57a1939b6cd8132a78f394a.
