And so it should. The man page says it is "a buggy program that
does fuzzy things ... Avoid it if you can.":

 There are several *fdisk programs around.  Each has its problems and
strengths.  Try  them in  the  order  cfdisk,  fdisk,  sfdisk.   (Indeed,
cfdisk is a beautiful program that has strict requirements on the partition
tables it accepts, and produces high  quality  parti- tion tables. Use it if
you can.  fdisk is a buggy program that does fuzzy things - usually it happens
to produce reasonable results. Its single advantage is that it has some support
for  BSD  disk labels and other non-DOS partition tables.  Avoid it if you can.
sfdisk is for hackers only - the user interface is terrible, but it is more
correct than  fdisk  and more powerful than both fdisk and cfdisk.  Moreover,
it can be used noninteractively.)

It's interesting that in the manpage, nobody has admitted authorship. ;-)
