System crash on Row(<empty string>)

[kaigai]

I could get a system crash on PostgreSQL v9.6 + pg_hint_plan 1.2.5 (for PGv9.6)
when I told the hint-clause below.

/*+
 Row()
 */

It is fundamentally a syntax error, so I expect it shall be ignored or aborted by error.
I guess something like list or cstring are not handled correctly in this corner case.

It is a long standing bug of the parser for Rows hint. Fixed it at the commit dd5ea96 and back-patched up to 94. Thanks for reporting.
