Please report all bugs you find in Bash. But first, you should make sure that it really is a bug, and that it appears in the latest version of Bash. The latest released version of Bash is always available for FTP from ftp://ftp.gnu.org/pub/gnu/bash/ and from http://git.savannah.gnu.org/cgit/bash.git/snapshot/bash-master.tar.gz.
Once you have determined that a bug actually exists, use the
bashbug command to submit a bug report or use the form at the
Bash project page.
If you have a fix, you are encouraged to submit that as well!
Suggestions and ‘philosophical’ bug reports may be mailed
to bug-bash@gnu.org or help-bash@gnu.org.
All bug reports should include:
bashbug inserts the first three items automatically into
the template it provides for filing a bug report.
Please send all reports concerning this manual to bug-bash@gnu.org.
