Thank you for the report.  Unfortunately seq uses floating point
numbers internally.  This has caused some problems in the resulting
implementation.

I can reproduce your problem on seq 5.97 in an old Debian Etch
machine.  However your seq 5.2.1 was released in 2004 and now five
years later there have been many improvements and bug fixes applied
since then.  So I think upstream this has already been fixed in later
versions for some time.

In any case this works for me with 6.10.  See this output.

  $ seq 9999997 10000005
  9999997
  9999998
  9999999
  10000000
  10000001
  10000002
  10000003
  10000004
  10000005

$ seq --version
