A syntax error on a variable assignment lead to $x being unset when `enable
-n "$x" was executed, which produced this error message:
./test.sh: line 22: enable: cannot find _struct in shared object :
/usr/bin/bash: undefined symbol: _struct
Repeat-By:
x="${1:='export'}"
./test.sh: line 19: $1: cannot assign in this way
readonly x
+ readonly x
declare -p x
+ declare -p x
declare -r x
enable -n "$x"
+ enable -n ''
