Thanks. ------------------------------------------------------------------------ [2008-11-18 18:23:15] asbjorn at lila dot io I just forgot to add that there is a bunch of traces available at http://asbjorn.it/pub/bugreports/php/fileinfo/dumps/ ------------------------------------------------------------------------ [2008-11-18 18:19:29] asbjorn at lila dot io Description: ------------ I ran the script with: php5 -n -e test.php I ran it in a loop like this: for i in seq 1 100; do php5 -n -e test.php; if [ $? != 0 ]; then echo; echo Crashed on run $i; echo ; break; fi; done We don't use MySQL for anything else than pastebin on that machine so we have just moved MySQL off that machine for now, since we primarily uses PgSQL. The PECL bug reporter doesn't support PHP 5.2.6, so I set it to 5.2.5. php5 -n -v output: PHP 5.2.6-5 with Suhosin-Patch 0.9.6.2 (cli) (built: Oct 5 2008 12:28:28) Copyright (c) 1997-2008 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies php -n -i output, test script, etc.: http://asbjorn.it/pub/bugreports/php/fileinfo/ I haven't had time to test it on PHP5.3 yet. Reproduce code: --------------- <?php // This script has a seg faults in at // *least* 1 out of 50 runs. I have a script that // consistenly fails. But I haven't been able to // replicate it in a small script. dl('mysql.so'); // or mysqli.so, but not pdo.so+pdo_mysql.so dl('fileinfo.so'); // the order doesn't mather echo "Initializing Fileinfo\n"; $finfo = new FInfo(FILEINFO_MIME); // If you don't access undefined variables // it doesn't seg faults. echo 'foo is'.(isset($foo)?'':' NOT')." set\n"; echo "The script continues...\n" // High risk of seg fault during shutdown ?> Expected result: ---------------- Initializing Fileinfo foo is NOT set The script continues... Actual result: -------------- Initializing Fileinfo foo is NOT set The script continues... Segmentation fault (core dumped) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=58418&edit=1
