| ================================================================================================ | |
| This is Rakudo Perl 6 running in the GNU debugger, which often allows the user to generate useful back- | |
| traces to debug or report issues in Rakudo, the MoarVM backend or the currently running code. | |
| This Rakudo version is 2018.06.479.g.0979.b.77 built on MoarVM version 2018.06.560.ge.446.a.67, | |
| running on linuxmint (18.3.Sylvia) / linux (4.10.0.38.generic) | |
| Type `bt full` to generate a backtrace if applicable, type `q` to quit or `help` for help. | |
