This issue comes up at random times.

Getting signal SIGABRT in the CharacterReader class.

public func consumeToAny(_ chars: [UnicodeScalar]) -> String { let start = pos while pos < input.endIndex { if chars.contains(input[pos]) { // signal pops up here. break } pos = input.index(after: pos) } return cacheString(start, pos) }
