Previous Comments: ------------------------------------------------------------------------ [2011-10-28 19:50:36] ralph at ralphschindler dot com This is the fix for the issue: https://github.com/ralphschindler/php- src/commit/5bf57e28b7090aaf0428a984b90a11d25c12b22e I will prepare a patch for trunk/5_3/5_4 along with tests. ------------------------------------------------------------------------ [2011-10-28 19:46:37] ralph at ralphschindler dot com Description: ------------ Stubs who's content before the __HALT_COMPILER(); registers between 1007 - 1023 bytes (or an interval thereof) will force the function phar_open_from_fp() to incorrectly throw an MAPPHAR_ALLOC_FAIL() or: Fatal error: Uncaught exception 'UnexpectedValueException' with message 'internal corruption of phar "xxx/test.phar" (__HALT_COMPILER(); not found)' in xxx/test.php:5 This is due to an incorrect index in the memmove() call inside the function that shifts the buffer to inspect the contents for the __HALT_COMPILER() token. THis bug is exposed when opening a phar and iterating the contents. Attached is a sample phar, test script, and patch Test script: --------------- <?php $phar = __DIR__ . '/test.phar'; foreach (new RecursiveIteratorIterator(new Phar($phar, null, 'test.phar')) as $item) { echo $item . PHP_EOL; } ?> Expected result: ---------------- Iterate the results. Actual result: -------------- Fatal error: Uncaught exception 'UnexpectedValueException' with message 'internal corruption of phar "xxx/test.phar" (__HALT_COMPILER(); not found)' in xxx/test.php:5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60164&edit=1
