works for me, on both 3.0.5 and 3.2.0rc3.

octave:1> fd = fopen( "test.bin" , "wb" ) ;
octave:2> for k = [ 1:300 ]

octave:3> fclose( fd ) ;
octave:4> stat("test.bin")
ans =
{
  dev =  2051
  ino =  14561678
  mode =  33188
  modestr = -rw-r--r--
  nlink =  1
  uid =  1000
  gid =  100
  rdev = 0
  size =  2.5166e+09
  atime =  1.2433e+09
  mtime =  1.2433e+09
  ctime =  1.2433e+09
  blksize =  4096
  blocks =  4920008
}

maybe upgrade will help.

cheers
