#18821 [Opn]: CLI crashes with 'echo "";' as with every other command as well

ID: 18821 Updated by: sander@php.net Reported By: eru@php.net Status: Open Bug Type: Reproducible crash Operating System: RedHat 7.3 w/ 2.4.18-5smp PHP Version: 4CVS-2002-08-09 New Comment: I've got the same problem on my local box. The problem disappears when configuring without debug. The problem is, that for some reason current points to 0x1 when current == l->tail, while it should point to 0x0. Previous Comments: ------------------------------------------------------------------------ [2002-08-09 06:33:23] eru@php.net ./configure --enable-debug (gdb) run -r 'echo "";' Starting program: /usr/local/src/cvs/php4/sapi/cli/php -r 'echo "";' Program received signal SIGSEGV, Segmentation fault. 0x0816313f in zend_llist_destroy (l=0x81f5020) at /usr/local/src/cvs/php4/Zend/zend_llist.c:110 110 next = current->next; same backtrace as last time... I tested various commands like php -r 'phpinfo();' and even php -r '' segfaults... ------------------------------------------------------------------------ [2002-08-09 02:36:16] edink@php.net Hm, cannot reproduce this with a simple configure line. Could you try to recompile with just ./configure --enable-dedug and see if it still crashes? If it doesn't could you try locating which extension causes the trouble? ------------------------------------------------------------------------ [2002-08-08 21:30:51] eru@php.net Dunno why it does, tested on a WinXP too with CVS from yesterday, works like a charm.
