Thanks for your response. 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:

I also tried Bash 3.00.16(11) with DLL version 1.5.21 and still had a
problem. I see this on several machines so it's not isolated to one.

Thanks for your help and any info you can provide,


I have tried this locally with 1.5.21 and bash 3.1.17-8 using the scripts
you provided and don't see the issue you report.  That's not to say that
there isn't an issue.  Only that I cannot reproduce it.  Maybe it's worthwhile
for you to review the output of 'cygcheck -srv' and see if something there
catches your attention.  If not, sending it to the list might spot something.
