Bug #71948 [NEW]: Variables by reference broken as of 7.0.5
From: dane dot tschi at gmail dot com
Operating system: Unix/OSX
PHP version: 7.0.5
Package: Variables related
Bug Type: Bug
Bug description:Variables by reference broken as of 7.0.5
Description:
------------
We tried upgrading from php 7.0.4 to 7.0.5. Unfortunately zendframework
stopped working. After debugging I came up with a reduced testcase that
reproduces the issue.
On php 7.0.4 it outputs the expected result, on 7.0.5 the wrong result.
This only happens if the switch-case is in there, if i replace it with
if/else it works.
Test script:
---------------
<?php
$tokenIndex = 0;
$tokens = [T_WHITESPACE, T_CLASS];
$tokenType = null;
$MACRO_TOKEN_ADVANCE = function () use (&$tokenType, &$tokenIndex,
$tokens) {
if (!isset($tokens[$tokenIndex])) return false;
$tokenType = $tokens[$tokenIndex++];
return $tokenType;
};
$MACRO_TOKEN_ADVANCE();
SCANNER_TOP:
switch($tokenType) {
case T_WHITESPACE: echo "whitespace"; break;
case T_CLASS: echo "class"; break;
}
if ($MACRO_TOKEN_ADVANCE() !== false) goto SCANNER_TOP;
Expected result:
----------------
whitespaceclass
Actual result:
--------------
whitespacewhitespace
