#47673 [NEW]: calling phpinfo() after tokenizer token_get_all() results in Segfault

From: serhii dot piddubchak at gmail dot com Operating system: FreeBSD 7.1 PHP version: 5.2.9 PHP Bug Type: Reproducible crash Bug description: calling phpinfo() after tokenizer token_get_all() results in Segfault Description: ------------ I'm getting a segmentation fault when trying to call phpinfo() after token_get_all(); phpinfo() works fine if called before token_get_all(); Here is a short information about my system: PHP Version 5.2.8 FreeBSD medved.hvosting.ua 7.1-RELEASE FreeBSD 7.1-RELEASE #0: Thu Jan 22 09:27:15 UTC 2009 root@free.ds:/usr/obj/usr/src/sys/ISPSYSTEM amd64 Build Date Feb 11 2009 15:20:04 Configure Command './configure' '--with-layout=GNU' '--with-config-file-scan-dir=/usr/local/etc/php' '--disable-all' '--enable-libxml' '--with-libxml-dir=/usr/local' '--with-pcre-regex=yes' '--enable-reflection' '--program-prefix=' '--enable-fastcgi' '--with-regex=php' '--with-zend-vm=CALL' '--enable-zend-multibyte' '--disable-ipv6' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' '--build=amd64-portbld-freebsd7.1' Server API CGI/FastCGI Also there is no extensions like eAccelerator or ZendOptimizer. Also I tried it on another FreeBSD 6.1 system, PHP5.2.8 configured as apache module, the bug wasn't reproducible. So, it looks like CGI/FastCGI or 64bit arch issue. Thanks in advance for any help. I can't install PHP5.2.9 because I don't own the server, it is a hosting account but I think it is reproducible in 5.2.9 since I didn't notice something relevant fixed in Changelog for 5.2.9 Reproduce code: --------------- <?php $tokens = token_get_all('/* comment */'); phpinfo(); ?> Expected result: ---------------- Expected result is to see full output from phpinfo() Actual result: -------------- The first summary table of phpinfo is printed, then process crashes with core dump. Here is a backtrace: This GDB was configured as "amd64-marcel-freebsd"...(no debugging symbols found)... Core was generated by `php-cgi'. Program terminated with signal 11, Segmentation fault. ...
