Yes this can happen, side effect of other changes fixing issues(IIRC incorrect
use of printf function family formatting) that can lead to the real life bugs.
To note this has effected rather few packages(10s of, which is in return few
percent of the Go package base) and this have been happening each Go devel
cycle and most of them being self explanatory. Fix or approach to it is
mentioned by the toolchain in the error message. Feel free to reach out if they
start popping up in bigger numbers or they look in anyway suspicious to you.
To update on the rebuild I have started to hit some issues with the mock's
chain build hitting locked yum/dnf cache that result in the crash of the chain
build(Have anyone seen this behavior?).
