Thanks for the set of flags. So this comes from the use of -Og, and the rest of the tree does not complain. The issue is that gcc complains about the buffer not being large enough, but %d only uses up to 2 characters so there is no overflow. In order to fix the issue it is fine enough to increase the buffer size to 28 bytes, so I would recommend to just do that. This is similar to the business done in 3a4b891. -- Michael
