0.19.0 pegs regression?

[lucian]

This used to work in 0.18.0, now it crashes run-time. Could anyone please 
confirm if working for them as to exclude my installation? Thanks.

    proc main =
      var pg = peg"\<(\d / [a-fA-F])+\>"
      
      let fnd = findAll("abc<5F>22<B9>0<6<DB>", pg)
      
      for f in fnd:
        echo f
    
    main()
