[jdv@new-host-2 p6-agent]$ perl6-gdb-m -Ilib t/01-basic.t 
================================================================================================
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 2017.06.170.gb.0.c.8.e.18 built on MoarVM version 2017.06.37.g.4.e.29.e.4.c,
running on fedora (25.Workstation.Edition) / linux (4.11.5.200.fc.25.x.86._.64)

Type `bt full` to generate a backtrace if applicable, type `q` to quit or `help` for help.
