Still seeing this error in Xcode 15 final.
@natecook1000 can you comment on this? It has been over a year and I still get a non-deterministic failure with this code.
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.
