The problem is here is that you build with "-Wfatal-errors", which enables strict type checking and disables implicit casts. If you can live without the option, please close with "WORKSFORME" otherwise we keep it open with low priority.
After a closer test it looks not to be solely the problem of "-Wfatal-errors" but of other options as well.
I don't see how Samba4 will ever compile with -Waggregate-return (given our use of DATA_BLOB).
