Bug #18526: assertion fails

From: horny@mail.az Operating system: Windows XP PHP version: 4.2.1 PHP Bug Type: Unknown/Other Function Bug description: assertion fails <?php assert_options(ASSERT_ACTIVE, '1'); assert_options(ASSERT_WARNING, '1'); assert_options(ASSERT_QUIET_EVAL, '0'); $AVAILABLE_LANGS = array('az' => 'az', 'ru' => 'ru', 'en' => 'en'); # as per RFC 1766 function func($predicate) { do { $freeflag = null; if (call_user_func($predicate, $freeflag) === FALSE) break; assert('!is_null($freeflag)'); } while (0); } class foo { function foo_method(&$freeflag) { $retval = (bool) rand() % 2; if ($retval) $freeflag = 1; return $retval; } } $foo_instance = new foo; func(array($foo_instance, 'foo_method')); ?> D:\>c:\php\php-cli haha.php Warning: Assertion "!is_null($freeflag)" failed in haha.php on line 14 It occurs *always* no matter what foo_method() returns, as if asserts() are happening asynchronously. If I instead change func() to function func($predicate) { $freeflag = null; if (call_user_func($predicate, $freeflag) === TRUE) assert('!is_null($freeflag)'); } The assertion doesn't fail.
