To test that the param susbtitution in "$@""${v%*/}" is ignored (on a
command line or in an assignment):
$ dash -c 'v=1/2; w="$@""${v#*/}"; echo "$@""${v#*/}" "$w"'
Note that the quoting has to be around each variable, that the first has
to be $@ and that the bug occurs with %, %%, #, or ## substring
processing.
Adding a string in between the 2 required vars does not change the
behaviour:
$ dash -c 'v=1/2; echo "$@"s$u"s${v#*/}"'
except by adding a string, even empty, inside the quoting of $@:
$ dash -c 'v=1/2; echo "$a$@""${v#*/}"'
