Description:
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
Thanks for the report. dlopen will succeed with a null pathname, but the
object will (obviously) not have the required loadable builtin info. Best
not to call it with a null pathname at all.
