redirect-append (>>) creates garbage-y file

[William Lebow]

I'm a long time cygwin user, but I am having the weirdest problem after installing on my new Dell laptop running Windows XP professional. I'd be grateful for any advice or hints from this group.

I am doing a simple redirect-append (>>, that is) to create a new file. When I do this the new file has twice as many characters as I expect and the first bunch of characters are seemingly garbage.

This only happens with ">>" and only if I am creating a new file.
Using ">>" to append to a file is no problem.
Using ">" to create a new file is not problem

So far this has not been reproducable on any other PC.

I am using the bash version 3.2.49(23)-release (i686-pc-wygwin) , with the 1007.1.0.0 cygwin1 dll-- see attached output from cygcheck.

Some examples follow::

#################################
#### Example 1
#### I expect 4 characters (including the terminator); I get 7
#### The first 3 characters are unwanted
  $ echo abc >> test1.txt
  $ wc test1.txt
  1 1 7 test1.txt
  $ cat test1.txt
  0▒▒abc

$ hexedit test1.txt
00000000   30 B5 A2 61  62 63 0A                                            0..abc.

#################################
#### Example 2
#### I expect 8 characters (including the terminator); I get 15
#### The first 7 characters are unwanted
  $ echo abcdefg >> test2.txt
  $ wc test2.txt
   1  1 15 test3.txt
  $ cat test2.txt
  ▒▒\zB▒▒abcdefg

hexedit test2.txt
00000000   AD EB 5C 7A  42 B6 C5 61  62 63 64 65  66 67 0A                  ..\zB..abcdefg.


#################################
#### Example 3
#### Use > instead of >> and I get exactly what I should get
  $ echo abc > test3.txt
  $ wc test3.txt
  1 1 4 test3.txt
  $ cat test3.txt
  abc



Many thanks for any help
