#32862 [Bgs]: session_register() causes Segmentation fault

ID: 32862 User updated by: svenl at haberer-online dot de Reported By: svenl at haberer-online dot de Status: Bogus Bug Type: Session related Operating System: SUSE Linux 9.2 PHP Version: 4.3.11 New Comment: Hi Tony, was just assuming these would work through minor revisons, as all my programs run fine when upgrading from original-suse PHP to my own re-compile of php 4.3.10 (to enable ODBC-support)... The extensions are original as from SUSE 9.2 Pro. And when upgrading to 4.3.11, I noted that session support was broken - assuming there would be a problem in this php version... Now I checked all extensions (using the demo-pograms from php-doc): - "bz2" causes a seg-fault for both 4.3.10+11 - "curl" works for both 4.3.10+11 - "ftp" works for both 4.3.10+11 - "gd" works for both 4.3.10+11 - "mysql" works for both 4.3.10+11 - "session" causes a seg-fault for 4.3.11 only - "zlib" works for both 4.3.10+11 Thus I if I understand you you correctly, I will have to re-compile all extensions for every upgrade in version ? ThanX, Sven Previous Comments: ------------------------------------------------------------------------ [2005-04-30 23:27:31] tony2001@php.net >Might there be some incompatibility ? Yes, of course. Where did you get that extensions compiled with one PHP version will work with another one? ------------------------------------------------------------------------ [2005-04-30 23:13:23] svenl at haberer-online dot de Hi Sniper, thanX for your quick reply... Sorry about not mentioning this earlier, but my session-support is inside an extension... Thus using exactly the same configure command for 4.3.10, sessions work fine (with register_globals = On, obviously). Perhaps the output of php_info helps: www.haberer-online.de/php/php4_3_10_info.htm www.haberer-online.de/php/php4_3_11_info.htm These are the two programs I use for testing: /// snip : session_test.php // <? $barney = "A big purple dinosaur."; session_register("barney"); echo "date=".date("H:i:s",time()); ?> <br><a href="session_test2.php">Next</a> //// end session_test.php // /// snip : session_test2.php // <? session_register("barney"); echo $barney."<br>"; echo "date=".date("H:i:s",time()); ?> //// end session_test2.php // with version 4.3.10, no errors get reported and the value set in the first script is reported in the second script... With v 4.3.11 I get the mentioned error messages. BTW, the only things I did was configure make make install - the extensions were not touched. Might there be some incompatibility ? The content of my extension dir looks like: ikarus: # pwd /usr/lib/php/extensions ikarus: # ll total 320 drwxr-xr-x 2 root root 224 Mar 20 23:00 . drwxr-xr-x 5 root root 160 Mar 20 23:39 .. -rwxr-xr-x 1 root root 15426 Oct 5 2004 bz2.so -rwxr-xr-x 1 root root 36096 Oct 5 2004 curl.so -rwxr-xr-x 1 root root 43584 Oct 5 2004 ftp.so -rwxr-xr-x 1 root root 93311 Oct 5 2004 gd.so -rwxr-xr-x 1 root root 49578 Oct 5 2004 mysql.so -rwxr-xr-x 1 root root 52726 Oct 5 2004 session.so -rwxr-xr-x 1 root root 28486 Oct 5 2004 zlib.so ThanX again for your assistance - hope its not a stupid mistake from my side... Sven ------------------------------------------------------------------------ [2005-04-28 08:28:40] sniper@php.net It can hardly work if you have '--disable-session' in your configure line. ------------------------------------------------------------------------ [2005-04-28 02:32:53] svenl at haberer-online dot de Actually the same problem exists if register_globals = Off ------------------------------------------------------------------------ [2005-04-28 02:22:23] svenl at haberer-online dot de Description: ------------ Hi, when calling session_register() using php 4.3.11 and apache 2.0.50, I get an Seg-Fault. When using $_SESSION, it works fine Using php 4.3.10 and exactly the same configuration, it worked fine. my config looks as follows: ./configure --prefix=/usr --datadir=/usr/share/php --mandir=/usr/share/man --bindir=/usr/bin --libdir=/usr/share --includedir=/usr/include --sysconfdir=/etc --with-_lib=lib --with-config-file-path=/etc --with-exec-dir=/usr/lib/php/bin --disable-debug --enable-inline-optimization --enable-memory-limit --enable-magic-quotes --enable-safe-mode --enable-sigchild --disable-ctype --disable-session --without-mysql --disable-cli --without-pear --with-openssl --with-apxs2=/usr/sbin/apxs2-prefork i586-suse-linux --with-unixODBC=/usr/lib/unixODBC php-ini: register_globals = On Reproduce code: --------------- Script 1: crashes <? $barney = "A big purple dinosaur."; session_register("barney"); echo "date=".date("H:i:s",time()); ?> Script 2: works <? $_SESSION["barney"] = "A big purple dinosaur."; echo "date=".date("H:i:s",time()); ?> Expected result: ---------------- both times I expect the time to be displayed Actual result: -------------- With the first script the browser shows nothing (FireFox) or complains that the server closed the connection (Konqueror). Also apache adds the following warning to the error_log: [date] [notice] child pid 30727 exit signal Segmentation fault (11) --- The second script shows the time as expected ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32862&edit=1
