Yes, I used "use strict" and "use warnings", but it changes nothing. I
can reproduce it using perlbot on Freenode (Perl 5.018001).

<GlitchMr> eval: sub array : lvalue { if (@array) {} else { @array
} } (array) = ()
<perlbot> GlitchMr: ERROR: Bizarre copy of ARRAY in block exit at (eval
1833) line 1.

I can also reproduce it on Codepad (using old version, 5.008, but it
confirms that this bug existed here for here for a long time) -
<http://codepad.org/x0KwLtUJ> (it says leave, but I blame old Perl
version), and ideone (with Perl 5.016002) - <http://ideone.com/02TLL7>.
