#32852 [Opn->Fbk]: Crash with singleton and __destruct
ID: 32852 Updated by: [EMAIL PROTECTED] Reported By: cox at idecnet dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: Linux PHP Version: 5.0.4 New Comment: I still can't reproduce this. I get same result with both HEAD and PHP_5_0 branches and also with the snapshot. Does it give same result if you make sure you don't load any php.ini: sapi/cli/php -n file.php What bison version do you have installed? What compiler (and version) ? Previous Comments: [2005-04-28 10:53:13] cox at idecnet dot com With today's CVS (5.1), it does not crash. But the output is: Output: i'm called i'm called i'm called i'm called The __destruct() function is called 4 times. With php5-STABLE-200504271035 (5.0.5dev): $ make distclean $ ./configure \ --prefix=/usr \ --with-config-file-path=/etc/php5 \ --enable-cli \ --disable-cgi \ --disable-pear \ --enable-debug Still the same output and same crash. [2005-04-28 00:25:57] [EMAIL PROTECTED] If you configure with --enable-debug (rm config.cache && ./configure + your options + --enable-debug && make clean && make) does it still crash? Are you sure you ARE using the latest CVS? (the snapshots might not be updated again..) [2005-04-27 23:25:44] [EMAIL PROTECTED] Still works fine here. Both with HEAD and 5.0.x. [2005-04-27 16:52:39] cox at idecnet dot com Versions and compile options for the two that crashes for me. In case it says something for you, if I remove the __destructor() function the code works good (also you see in the output this function is being called twice). 5.0.4 ~~~ PHP 5.0.4 (cli) (built: Apr 27 2005 11:48:13) Configure Command => './configure' '--prefix=/usr' '--with-config-file-path=/etc/php5' '--with-xml' '--with-zlib' '--with-gd' '--enable-gd-native-ttf' '--with-freetype-dir' '--with-png-dir' '--with-jpeg-dir' '--disable-pear' '--with-mysql=/usr' '--with-imap=/usr/include/imap' '--with-imap-ssl' '--with-kerberos' '--with-gettext' '--enable-ftp' '--with-dom' '--with-mhash' '--with-mcrypt' '--enable-cli' '--enable-sockets' '--enable-sigchild' '--enable-pcntl' '--enable-shmop' '--enable-posix' '--enable-bcmath' '--with-xmlrpc' '--with-mime-magic' '--disable-cgi' 5.0.5 Snapshot Stable ~~~ PHP 5.0.5-dev (cli) (built: Apr 27 2005 13:47:32) (DEBUG) Configure Command => './configure' '--prefix=/usr' '--with-config-file-path=/etc/php5' '--with-xml' '--with-zlib' '--with-gd' '--enable-gd-native-ttf' '--with-freetype-dir' '--with-png-dir' '--with-jpeg-dir' '--disable-pear' '--with-mysql=/usr' '--with-imap=/usr/include/imap' '--with-imap-ssl' '--with-kerberos' '--with-gettext' '--enable-ftp' '--with-dom' '--with-mhash' '--with-mcrypt' '--enable-cli' '--enable-sockets' '--enable-sigchild' '--enable-pcntl' '--enable-shmop' '--enable-posix' '--enable-bcmath' '--with-xmlrpc' '--with-mime-magic' '--disable-cgi' '--enable-debug' [2005-04-27 14:41:26] [EMAIL PROTECTED] For some reason it doesn't crash for me..did you use --enable-debug ?
