Not exactly the same problem, though. It seems php_stream_open_for_zend() does not mmap() enough for ZEND_MMAP_AHEAD (PHP_STREAM_OPTION_MMAP_API in plain_wrapper adjusts the mmap length to the filesize, so ignoring ZEND_MMAP_AHEAD), and this may crash when the parser reads ahead of the mmap()ed region. ------------------------------------------------------------------------ [2009-04-21 11:50:51] ninzya at inbox dot lv PHP is installed as apache module. No fancy filtering, default php/apache installation. All php modules disabled. Bug hits only if file size is 8KB exactly (8192 bytes). PHP 5.2.9 also is affected. By the way, Apache 2.2 is not affected. Seems this is apache 2.0 specific problem. Don't know where to post this issue, here, or in Apache bugtracker. ------------------------------------------------------------------------ [2009-04-21 11:40:31] j...@php.net Which apache module? Do you have some fancy filtering going on? Does this happen with PHP 5.2.9 ? Do you have any shared extensions loaded? Any Zend extensions like debugger or cache? (disable those and retry) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
