I do not know the solution to your problem, but I added a print to your death sub:
print "removed=$removed, ", scalar @chroma, "\n";
splice (@chroma, $removed, 1);
This gives you more info about why you get the splice warnings.
You can also add
use diagnostics; which explains your
splice warning in more detail:
splice() offset past end of array at foo.pl line 154 (#1)
(W misc) You attempted to specify an offset that was past the end
+of
the array passed to splice(). Splicing will instead commence at th
+e end
of the array, rather than past it. If this isn't what you want, tr
+y
explicitly pre-extending the array by assigning $#array = $offset.
+ See
perlfunc/splice.
Hope this helps.
