ID: 60976 User updated by: xrstf-misc at yahoo 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: 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. Previous Comments: ------------------------------------------------------------------------ [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) ------------------------------------------------------------------------ [2012-02-04 07:39:19] paj...@php.net Ah you already did. Which EOL do you use on your original script? Unix or windows ones? Maybe zip it and post a link to the zip file, so the contents won't be altered (lexer bug). ------------------------------------------------------------------------ [2012-02-04 07:37:39] paj...@php.net Please provide us the full script you use to reprodruce the crash. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
