ID: 60976 Comment by: arjen at react dot com Reported by: xrstf-misc at yahoo dot com Summary: PHP crashes sometimes while parsing Status: Open Type: Bug Package: Reproducible crash Operating System: Win7x64 PHP Version: 5.3.10 Block user comment: N Private report: N New Comment: Bug https://bugs.php.net/bug.php?id=48034 is about 8192 bytes long scripts. Previous Comments: ------------------------------------------------------------------------ [2012-03-13 19:42:42] pete dot walker at cap2 dot co dot uk I'm also suffering from this issue. I had phpunit randomly crashing. Traced the problem using xdebug - I'm using the Database YAML extension (PHPUnit_Extensions_Database_DataSet_YamlDataSet), and it uses the include statement to load the YAML files. The YAML file knocking everything over was exactly 8192 bytes long (and ended with whitespace, but not \n). ------------------------------------------------------------------------ [2012-02-10 01:50:11] xrstf-misc at yahoo dot com This is actually a good hint by hanssen at aeteurope dot nl: I too had some cases where a generated cache file (containing "<?php $data = var_export(...)") would crash PHP when it was exactly 4096 Byte in size. ------------------------------------------------------------------------ [2012-02-09 13:59:24] hanssen at aeteurope dot nl I experience an issue which I think is caused by the same bug (PHP crashes in line 3182 of Zend/zend_language_scanner.c (contains "if ((yych = *YYCURSOR) == '\n') goto yy203;", part of function lex_scan()). In my case I call php_strip_whitespace() on a PHP file with a length of exactly 4096 bytes (the same length as the problem file reported by the original author of this bug) and where the file ends with "?>" without trailing newline. Inspection of lines 3181 and 3182 of Zend/zend_language_scanner.c reveals YYCURSOR being advanced one byte and a '\n' being expected, which fails here because it attempts to read memory beyond allocated memory. ------------------------------------------------------------------------ [2012-02-06 17:23:08] giunta dot gaetano at gmail dot com I also have php crashes - win7 64, apache 2.2.21 from apache lounge. No error messages left in either php or apache logs - just a "server reset connection" error from the browser. The code ran fine up to php 5.3.8 (did not test with 539). It involves executing a custom page within eZPublish, it is hard for me to trace it to a single php file / command and attach it here... ------------------------------------------------------------------------ [2012-02-05 15:19:32] xrstf-misc at yahoo dot com Here is the original file, wrapped in an 7z archive: http://www.xrstf.de/bug60976.7z (1KB) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
