PHP NumberFormatter and Currency, can't set precision

Question

I want to set a precision of 0 when using the NumberFormatter PHP class (from Intl extension) with currency. However I've got some strange result. Here:

$numberFormatter = new NumberFormatter('en-US', NumberFormatter::CURRENCY);
$numberFormatter->setAttribute(NumberFormatter::FRACTION_DIGITS, 0);

echo $numberFormatter->formatCurrency('45', 'USD');

It outputs $45, which is what I want. However, if I change the currency to EUR with the same settings:

echo $numberFormatter->formatCurrency('45', 'EUR');

It outputs €45.00 (although I explicitly set to have a precision of zero).

Even more strange, if I set the locale to fr-FR, it outputs the number as expected:

$numberFormatter = new NumberFormatter('fr-FR', NumberFormatter::CURRENCY);
$numberFormatter->setAttribute(NumberFormatter::FRACTION_DIGITS, 0);

echo $numberFormatter->formatCurrency('45', 'EUR');

It outputs 45 €.

Is this a bug?

I confirm this is an ICU bug in 4.4.x branch.
Consider upgrading libicu, 4.8.x gives correct result
