fflush(3) on fseeko(3).

Browse source 
This caused a corruption of the resulting file if the program fwrite some
data that is buffered, then fseeks, and then fflushes. The fwrite will then
happen at the wrong memory location. Flushing in fseeko(3) fixes the problem
but it may cause violate some standard or just be inefficient.
