Regex non-deterministicly fails #639
Description
Description
Please see the attached playground. The regex in it will work sometimes and fail other times over the same data set. It fails because it isn't greedily consuming a ZeroOrMore.
Steps to reproduce
Open the enclosed playground. Keep changing portions (to cause a recompile) until it fails.
Expected behavior
The ZeroOrMores should consume the entire matching string in the whole match. Also, the same string processed by the same regex should always either fail or not fail.
