Notice how it says �name too l�. It should be �name too long� but it does
not fit. And if we add more digits​:
say ('a' x 10000).IO.open;

Result​:
Malformed UTF-8 at line 1 col 1029

I don't get the UTF-8 malformed error. Bisectable output​:

<samcv> bisectable6, say ('a' x 10000).IO.open;
<bisectable6> samcv, Bisecting by output (old=2015.12 new=f0c3bf7) because on both starting points the exit code is 1
<bisectable6> samcv, bisect log​: https://gist.github.com/da75432d7785e4bdc0c0a74e6084b49c
<bisectable6> samcv, (2015-12-25) rakudo/rakudo@07fecb5

Seems to show it has been fixed for a while.

Maybe this should change to a LTA due to the error message?

From @AlexDaniel

An important line from bisectable output was omitted :)

<bisectable> samcv, The result looks a bit unrealistic, doesn't it? Most probably the output is different on every commit (e.g. ï½¢bisect​: say randï½£)

We can try this​:

<AlexDaniel> c​: releases say ('a' x 10000).IO.open
<committable6> AlexDaniel, https://gist.github.com/0727db8b695fbed572cf4b9cd9fa6edc

Looking at the output, we can see that it was changed somewhere between 2017.03 and 2017.04.3, so actually it is a fairly recent fix.

I tried to narrow it down with a bot, but couldn't. Not that it matters much, just wanted to note that it is not as new.
