The input file for this problem is ≈15 MB so please bear with external link: https://files.progarm.org/golfed.gz (1.6 MB compressed) Command: perl6 -ne 'say $++' golfed # or perl6 -ne 'say $++' < golfed Result: 0 1 2 … … … 257568 257569 257570 Malformed UTF-8 in block <unit> at -e line 1 There's no malformed UTF-8 in the file. And if you don't believe me, try this: cat golfed | perl6 -ne 'say $++' There are at least three possible outcomes (it is not as stable as previous examples): (*) Fails after 257570, just like in the previous example (*) Fails after 121712 (*) No error, goes through the whole file just fine <geekosaur> sounds more likely to be I/O related than unicode related <geekosaur> like it's dropping bytes on the floor and if the utf8 decoder was in (or lands in) the middle of a sequence, boom IRC log: https://irclog.perlgeek.de/perl6-dev/2017-08-26#i_15071860 This issue may be related: https://gist.github.com/coke/3feef738886b1e5af79a1ca636146075
