Sorry if this causes confusion, but I thought it might be better to start a new bug after I realized that so many things had changed (different OS, different PHP version (4 vs. 5), etc.) As well, I forgot my configure line (found at very bottom of post)... I have some websites that run fine, with DB connection through mysqli. However, browsing to the phpMyAdmin page causes a segfault. I am using phpMyAdmin-2.6.0-pl3. Previously, before it would segfault, phpMyAdmin would not even let me login, returning me this error: "SELECT VERSION() as version", empty result set returned (or something like that). So I have never had phpMyAdmin working at all, but it never segfaulted before. I am really confused, and hopefully a somewhat serious bug can be found of this, as I have been having several random segfault parties (times where certain code segfaults for no apparent reason). A little more info: I am running a AMD 64 3200+, 512MB RAM, SuSE 9.1 (kernel-2.6.4, glibc-2.3.3) Thanks for any help/fixes! -Andrew './configure' '--prefix=/usr/local/php5' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-libxml-dir=/usr/local/lib' '--with-zlib' '--with-zlib-dir=/usr/local/lib' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--enable-sockets' '--enable-exif' Reproduce code: --------------- Not sure. If anybody wants me to debug phpMyAdmin to try to make this process easier, then I can try that... but I'm hoping the backtrace might be enough. This information might be valuable: phpMyAdmin acutally works enough to ask me for my username/password. If I enter the wrong username/password, it works fine, as in it keeps asking me for u/p. However, once I enter the *correct* u/p, it then segfaults. I will provide some pseudo code of the PMA_DBI_postConnect() function called after a succesful connect: <?php if (!defined('PMA_MYSQL_INT_VERSION')) { // this is where it used to not work before (SELECT VERSION() as version) $result = query("SELECT VERSION() as version"); if ($result IS valid) { fetch_row(); parse the version number; } if (mysql > 4.1) { // true for me! change lang and charset options based on user info; call SET NAMES and SET CHARACTER SET; // if provided } else { // not true for me include phpmyadmin charset_conversion library; } } ?> Expected result: ---------------- phpMyAdmin to not cause a segfault, at least give me the other error from before... (SELECT VERSION() as version returned empty result set) NOT segfault Actual result: -------------- zend_object_store_get_object (zobject=0x0) at /usr/local/src/php5-STABLE-200412171930/Zend/zend_objects_API.c:202 202 return EG(objects_store).object_buckets[handle].bucket.obj.object;

I don't know if this will assist or is related at all, but I would often get segfaults if I threw a new CException (a class extending Exception) inside or nested inside a __destruct. I don't know if this is an "intentional" behavior, but I changed my code to not call those functions/etc. from a __destruct. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31161&edit=1
