Did you test Bash 5.0? Because that's where the current bug fixes are going to.
I don't see Chet releasing a new version of 4.4 to fix something that's already
fixed there.

address@hidden:~/src/gnu/bash$ cat /tmp/script 
echo $BASH_VERSION
set -- "  foo  "    "  bar  baz  "  "  quux  "
unset IFS
a=$*
b="$*"
printf '[%s]' "$a" "$b"; echo

address@hidden:~/src/gnu/bash$ bash /tmp/script 
4.4.19(1)-release
[foo bar baz quux][  foo     bar  baz     quux  ]

address@hidden:~/src/gnu/bash$ ./bash /tmp/script 
5.0.0(1)-alpha
[  foo     bar  baz     quux  ][  foo     bar  baz     quux  ]
