This is a bug report for perl from bulk88@hotmail.com,
generated with the help of perlbug 1.40 running under perl 5.19.9.


-----------------------------------------------------------------
[Please describe your issue here]

I noticed this strange message during a harness run from utf8cache.t, so 
I investigated. It was mentioned once in 
http://www.nntp.perl.org/group/perl.perl5.porters/2011/08/msg176054.html 
and it got 1 response in 
http://www.nntp.perl.org/group/perl.perl5.porters/2011/08/msg176059.html  .

'-' is not recognized as an internal or external command,
operable program or batch file.
ok 1
ok 2 - quadratic pos
ok 3 - get-magic resets utf8cache on match vars
ok 4 - get-magic resets utf8cache on LVALUEs
ok 5 - get-magic resets uf8cache on defelems
ok 6 - pos on overloaded utf8 toggler
ok 7 - pos on overloaded utf8 toggler (again)
ok 8 - utf8 cache + overloading does not confuse substr lvalues
ok 9 - utf8 cache + overloading does not confuse substr lvalues (again)
ok 10 - utf8 cache + overloading does not confuse substr lvalue assignment
ok 11 - utf8 cache + overload does not confuse substr lv assignment (again)
ok 12 - no utf8 pos cache on globs
ok 13 - no utf8 pos cache on references
ok 14 - no utf8 length cache on globs

 From utf8cache.t

-------------------------------------------------------------------
my $pid = open CHILD, '-|';
die "kablam: $!\n" unless defined $pid;
unless ($pid) {
     open STDERR, ">&STDOUT";
     $a = "hello \x{1234}";
-------------------------------------------------------------------

$pid is true, and is a PID to the following process,
-------------------------------------------------------------------
Path: "C:\WINDOWS\system32\cmd.exe"
Command Line: "cmd.exe /x/d/c -"
-------------------------------------------------------------------

I am not sure if the CHILD FH actually works (IDK what works means). Its 
only use in utf8cache.t is
-------------------------------------------------------------------
{ local $/; $_ = <CHILD> }
-------------------------------------------------------------------

The '-|' is from day 1 of this test, from 
http://perl5.git.perl.org/perl.git/commitdiff/fa421ef92a7e8058000e870bee22bbe09d7055c9 
added in 5.11.2. I am not sure what this test does, but it does pass in 
the end. It probably doesn't do what is intended on *nix on Windows 
though and something needs to change.

[Please do not change anything below this line]
