I believe you have to initialize the array in order. Switching these two lines:

:) nope, this is perl, the order doesn't matter

Looks like some recent optimization has backfired, again

    That's strange. Using OP's code on 5.24.0, it breaks. If I swap those two lines around, it works fine. I've never had an issue with assigning values to an array out of order before, but in this case, it definitely matters :)


    use warnings; use strict; my $value = "A\tB\tC\tD\tE\tF\t\t\t\t\t\t"; my @flds = split(/\t/, $value); $flds[8] = 0; $flds[16] = undef; print scalar @flds; __END__ 17


    use warnings; use strict; my $value = "A\tB\tC\tD\tE\tF\t\t\t\t\t\t"; my @flds = split(/\t/, $value); $flds[16] = undef; $flds[8] = 0; print scalar @flds; __END__ Modification of a read-only value attempted at line 7.
