I'm still running into this with 1.5.21. The background process has to be ran from a script, as in the example I provided above. If you kick the script from the command line, this problem does not occur. If you run the example above with ./file1.sh, you should see the problem. I didn't run into this with DLL version 1.5.18. Here is the bash and DLL versions of both: Problem DLL and Bash versions: $ bash --version GNU bash, version 3.1.17(8)-release (i686-pc-cygwin) Copyright (C) 2005 Free Software Foundation, Inc.

I see this on several machines so it's not isolated to one.
