Thanks for the report. The problem should be fixed by r3553.

Each Query subclass has a custom to_string() method defined. It's
imperfect (and definitely not for round-trip serialization), but
that's what I use to debug,and in this case it worked fine. When a
QueryParser with a default boolop of 'AND' parsed this string:
a OR b OR c
... the output of $query_parser->tree($qstring)->to_string looked like
this...
((a OR b) AND c)
... and it was easy to identify the problematic code in
QueryParser.c. After r3553, to_string yields this, which is correct:
(a OR b OR c)
