In the case of what's actually being called, the class is derived from mysqli. I haven't done extensive testing, but I was getting segfaults with both array_map and array_filter. It seems to be a general callback-related issue. Dual Opteron Kernel is SMP + 64bit Configure: ./configure \ --with-pgsql \ --with-xmlrpc \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-mysql=/usr --with-mysqli=/usr/bin/mysql_config \ --prefix=/usr/local/apache2/php \ --with-config-file-path=/usr/local/apache2/php \ --enable-force-cgi-redirect \ --disable-magic-quotes \ --with-curl \ --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-freetype-dir=/usr/lib --with-zlib-dir=/usr/lib Reproduce code: --------------- <?php class Faulty { function __call($Method,$Args) { switch($Method) { case 'seg': echo "I hate me"; break; } } function NormalMethod($Args) { echo "I heart me"; } } $Faulty = new Faulty(); $Array = array('Some junk','Some other junk'); // This causes a seg fault. $Failure = array_map(array($Faulty,'seg'),$Array); // This does not. $Failure = array_map(array($Faulty,'NormalMethod'),$Array); ?> Expected result: ---------------- Not seg faulting. Actual result: -------------- Segfaulting. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34260&edit=1
