The error message is a bit misleading but there's indeed an issue. You cannot serialize 1.01336003777999994e+23, 1225970000 or 1962330000123456 with the default %24.15f formatting used by the shapefile driver when there's no explicit width/precision in the source dataset. Here there's no real corruption are decimals are removed, but those numbers are no longer 24.15 and thus a pedantic reader could complain. There will be always issue when converting from IEEE754 (GPKG) to decimal (DBF). We could potentially have an ogr2ogr option that would do a full scan of the input dataset to determine the best formatting, but in the meantime you can do that manually:

ogr2ogr out.shp in.gpkg -sql "select cast(nonstructu as numeric(30,5)) from example" -overwrite -dialect ogrsql

Merci Even, indeed, I think that fixing the warning would be a good solution.
