[PHP-DEV] strange php_stream_from_zval requires return_value

[Arnold Daniels]

Hi,

I've noticed that building an extension will fail when using macro 
php_stream_from_zval and there is not return_value variable within the 
scope.

/root/php-5.1.6/ext/hello/hello.c: In function `streamit':
/root/php-5.1.6/ext/hello/hello.c:58: error: `return_value' undeclared 
(first use in this function)
/root/php-5.1.6/ext/hello/hello.c:58: error: (Each undeclared identifier 
is reported only once
/root/php-5.1.6/ext/hello/hello.c:58: error: for each function it 
appears in.)

when building

void streamit(zval * zstream TSRMLS_DC)
{
   //zval *return_value;  /* Will work if I uncomment this line */
   php_stream *stream;

   php_stream_from_zval(stream, &zstream);
   php_stream_write(stream, "hello\n", 6);
}

PHP_FUNCTION(hello_stream)
{
   zval *zstream;

   if (FAILURE == zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", 
&zstream))
       return;

   streamit(zstream TSRMLS_CC);

   RETURN_TRUE;
}

When return_value is added, the function will work without a problem.

I'm not sure whether this is bug or expected behavior and if I should 
use the bug reporting site or just post it here on the list. Anyhow it 
looks strange to me.

Best regards,
Arnold
