Matching everything in a subexpression loops infinitely

[rihardsk]

I made a simple grammar

grammar = \
        """
        rule <- (subexpression)+;
        subexpression <- r'^.*$';
        """

and tried to parse a simple text like so

from arpeggio.peg import ParserPEG
parser = ParserPEG(grammar, "rule")
parsed = parser.parse("something simple")

And the process never finishes. It just goes on parsing, steadily filling up the free memory.
