In testing this, I've noticed that the cygport install sub-command is
rather noisy on some binaries, due to its use of undefined behavior in
$() that causes the new bash to emit a warning:
/usr/share/cygport/lib/src_postinst.cygpart: line 970: warning: command
substitution: ignored null byte in input
/usr/share/cygport/lib/src_postinst.cygpart: line 977: warning: command
substitution: ignored null byte in input
A simple solution would be:
- case $(tail -c 12 "${exe}") in
+ case $(tail -c 12 "${exe}" | tr -d \\0) in
I'll wait to promote bash 4.4 to current until after I know if it is
worth waiting for a speedy cygport update.
