Bug description: php crashes with big scripts
Description:
------------
Giving it a large script, PHP 4.3.6 crashes during parsing it.
The stacktrace is as follows:
(gdb) bt
#0 0x081a5be6 in execute (op_array=0x8322c3c)
at /usr/src/kundenserver/php-4.3.6/Zend/zend_execute.c:2007
#1 0x08191598 in zend_execute_scripts (type=8, retval=0x0, file_count=3)
at /usr/src/kundenserver/php-4.3.6/Zend/zend.c:886
#2 0x0816a933 in php_execute_script (primary_file=0xbffffa38)
at /usr/src/kundenserver/php-4.3.6/main/main.c:1731
#3 0x081a9fd3 in main (argc=2, argv=0xbffffab4)
at /usr/src/kundenserver/php-4.3.6/sapi/cgi/cgi_main.c:1592
(gdb)
You can find a core file under
http://www.andigross.de/phpcrash/core.gz
and the binary under
http://www.andigross.de/phpcrash/phpbinary
A phpinfo is under
http://www.andigross.de/phpcrash/phpinfo.html
the configure-line is:
./configure --with-zlib --enable-debug --enable-safe-mode=no
--enable-discard-path=no --enable-track-vars --enable-force-cgi-redirect
--enable-memory-limit --enable-trans-sid --enable-shmop --with-openssl
--enable-xslt --with-xslt-sablot --with-dom --with-dom-xslt
--with-dom-exslt
The only modification to php.ini is:
memory_limit = 90M;
Compiler ist gcc 2.95.4.
Reproduce code:
---------------
You can find the code here:
http://www.andigross.de/phpcrash/testdaten.php.txt
Of curse, this is a very simple one to show the problem.
The problem also occurs with "more useful" scripts.
The application that caused the problem does something like
$big_text="Huge PHP source";
eval($big_text);
Expected result:
----------------
The script produces no output.
With PHP 4.2.3 it works fine.
Actual result:
--------------
