setlocale() call issues PHP Warning on CentOS 6.4, PHP 5.4.13

I'm getting a PHP Warning from csv/src/Goodby/CSV/Import/Standard/Lexer.php line 60:

PHP Warning:  setlocale(): Specified locale name is too long

I wrote a little test script to see what's getting passed to setlocale():

<?php
$originalLocale = setlocale(LC_ALL, '0');
echo "$originalLocale\n";

This outputs:

LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=en_US.UTF-8;LC_ADDRESS=en_US.UTF-8;LC_TELEPHONE=en_US.UTF-8;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=en_US.UTF-8

From ext/standard/string.c in the PHP source, I see:

if (Z_STRLEN_PP(plocale) >= 255) {
    php_error_docref(NULL TSRMLS_CC, E_WARNING, "Specified locale name is too long");
    break;
}

It appears this would be correct:

setlocale(LC_ALL, 'en_US.UTF-8');

But that's not portable... maybe we can parse $originalLocale and pass in an array to setlocale()?
