Description:
Fulltext parser plugin is called recursively: ftb_find_relevance* calls ftb_check_phrase*.
But the ftb_check_phrase* uses the same param as ftb_find_relevance*.
It means that when the latter wants to continue, the former has garbled the state of the parser plugin.

How to repeat:
 

Suggested fix:
Use different param's structures for ftb_find_relevance* and ftb_check_phrase*.

pushed to.  Thanks.

5.1.9.

Let's say "for fulltext search in a boolean mode, and when fulltext parser plugin was used, a MYSQL_FTPARSER_PARAM::ftparser_state could've been corrupted by recursive calls to the plugin"

Noted in 5.1.9 changelog, using Serg's comment. :-)
