busybox 1.24.1 ash regression

[Natanael Copa]

Hi,

musl's configure script fails with busybox 1.24.1 ash:

./configure: line 50: syntax error: unexpected "}"

The relevant code from the script

quote () {
tr '\n' ' ' <<EOF | grep '^[-[:alnum:]_=,./:]* $' >/dev/null 2>&1 && { echo "$1" ; return 0 ; }
$1
EOF
printf %s\\n "$1" | sed -e "s/'/'\\\\''/g" -e "1s/^/'/" -e "\$s/\$/'/" -e "s#^'\([-[:alnum:]_,./:]*\)=\(.*\)\$#\1='\2#"
}

It is the "tr ... <<EOF | grep .. && { ... }" that triggers it.

Simplfied test case:


foo () {
tr '\n' ' ' <<EOF | grep '.*' && { echo "$1" ; return 0 ; }
$1
EOF
}

foo "bar"


The simplified testcase works with bash, dash and busybox 1.23 ash, but
fails with busybox 1.24.1.
