Should work.
Does work with 5.10.1 and 5.12.1:
$ perl -e'print "foo,bar,baz\r\n";' > myfile.csv
$ perl -e'
use strict;
use warnings;
use open IN => ":crlf";
while (<>) {
die ("Carriage return in $ARGV") if (/\r/);
}
open (INPUT, "myfile.csv") or die ("Can'\''t open myfile.csv");
while (<INPUT>) {
die("Carriage return in myfile.csv") if (/\r/);
}
print "ok\n";
' myfile.csv
ok
Are you sure there are no CR other than right before a LF?
if (/\r/) {
require Data::Dumper;
local $Data::Dumper::Useqq = 1;
local $Data::Dumper::Terse = 1;
local $Data::Dumper::Indent = 0;
die ("Carriage return in myfile.csv " . Data::Dumper::Dumper(
+$_));
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
