I'm afraid this is indeed caused by the talloc tidyup as one can
perfectly reproduce it wih the following patch for smbtorture (call
bin/smbtorture ncacn_np:lo local.file.file_lines_parse). I guess we need
to set up some warning signs around file_lines_parse() expressing that
it takes talloced content and that one should not free the separated
lines array separately.
