[BUG] GC collects argv aka P0

[Leopold Toetsch]

Hi,

examples/life-ar.p6 uses a rather lengthy initialisation

    my  @world = (
        0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
         ...
        }; # 512 values

then tries to figure out, how many generations to run:

    my $gen = @ARGS[0] || 512;

at this point, @ARGS[0] aka P0[1] aka argv[1] is already dead:

$ perl6 -k examples/life-ar.p6 5
Running  generations
........^^

- It's not a perl6 problem
- inserting "collectoff" at the start of life-ar.imc avoids the bug:

$ perl6 examples/life-ar.imc 5
Running 5 generations

I hope someone of the GC hackers out there can find a solution.

TIA,
