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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
