Yeah. Man perldiag says:

       Split loop
           (P) The split was looping infinitely.  (Obviously, a
           split shouldn't iterate more times than there are
           characters of input, which is what happened.)  See the
           split entry in the perlfunc manpage.

A quick grep through the source shows this:

	[perl/perl-5.6.1]zapff*> rg "split loop"
	./pod/perldiag.pod:3060:=item Split loop
	./pp.c:5307:    DIE(aTHX_ "Split loop");

which is a piece of code in pp.c that says:

    iters = (SP - PL_stack_base) - base;
    if (iters > maxiters)
        DIE(aTHX_ "Split loop");

which is a debug statement that should never fire. So a bug report should be
filed with the "perlbug" command.

For what it's worth, I have this:


in my environment specificly to avoid some UTF-8isms. Not because I
hate UTF-* - I _like_ UTF-8 and think it's the Right Thing. But some
apps aren't ready for it yet.

Through and through the world is infested with quantity. To talk sense is to
talk quantities. It is no use saying the nation is large- how large? It is no
use saying that radium is scarce- how scarce? You can not evade quantity. You
may fly to poetry and music and quantity and number will face you in your
rythmns and your octaves.	- Alfred North Whitehead
