zephir_update_static_property_ce_cache in the compiler

[sjinks]

StaticProperty::assignStatic:

if ($compilationContext->insideCycle) {
    $propertyCache = $compilationContext->symbolTable->getTempVariableForWrite('zend_property_info', $compilationContext);
    $propertyCache->setMustInitNull(true);
    $propertyCache->setReusable(false);
    $codePrinter->output('zephir_update_static_property_ce_cache(' . $classEntry .', SL("' . $property . '"), &' . $tempVariable->getName() . ', &' . $propertyCache->getName() . ' TSRMLS_CC);');
} else {
     $compilationContext->backend->updateStaticProperty($classEntry, $property, $tempVariable, $compilationContext);
}

However, zephir_update_static_property_ce_cache is available only in ZE2 kernel.

Code to reproduce:

namespace Bug;

class StaticPropertyAccess
{

    protected static doubleVar = 0.0;

    public static function mutateDoubleVarInsideCycle() -> double
    {
        var i;

        for _ in range(0, 3) {
            let i = 3.14;
            let self::doubleVar = i;
        }

        return self::doubleVar;
    }
}
