#27342 [Opn]: zend_fetch_debug_backtrace segfault

ID: 27342 Updated by: nlopess@php.net Reported By: nlopess@php.net Status: Open Bug Type: Zend Engine 2 problem Operating System: win32 only PHP Version: 5CVS-2004-02-23 (dev) New Comment: I've compiled with Cygwin/gcc. Maybe the problem is in the microsoft VC compiler... Previous Comments: ------------------------------------------------------------------------ [2004-02-24 12:05:05] sniper@php.net well..then there's surely something wrong with the snaps since those won't work but self-compiled one works? :) ------------------------------------------------------------------------ [2004-02-24 10:00:01] edink@php.net Just FYI, snaps box is not for debug purposes. Its "if we were releasing PHP today you would get this". ------------------------------------------------------------------------ [2004-02-24 06:36:45] nlopess@php.net I've compiled PHP my self in cygwin (instead of using a snapshot from snaps.php.net) It just outputs: $ gdb php-debug (..) (gdb) run bug.php Starting program: /home/Nuno/php5/sapi/cli/php-debug.exe bug.php Fatal error: Uncaught exception 'tidy_exception' with message 'Unknown Tidy Conf iguration Option 'foo'' in /home/Nuno/php5/sapi/cli/bug.php:6 Stack trace: #0 {main} thrown in /home/Nuno/php5/sapi/cli/bug.php on line 6 Program exited with code 0377. (gdb) bt No stack. I think this doesn't help much, but I think snaps.php.net should distribute binaries with DEBUG symbols (as it is for debugging purposes). It seems it only segfaults with the binary from snaps.php.net. If you send me a snapshot with DEBUG symbols built in that machine, I may test it. ------------------------------------------------------------------------ [2004-02-23 13:20:09] sniper@php.net You need to get better backtrace. (dunno how you enable debug symbols in there) Tidy throws an exception with your code, and seems like that somehow crashes on windows. Maybe ZTS related..dunno. ------------------------------------------------------------------------ [2004-02-23 09:33:33] nlopess@php.net Hi sniper! Using latest snapshot from snaps.php.net, I still receive a segfault: Program received signal SIGSEGV, Segmentation fault. 0x1000a974 in zend_fetch_debug_backtrace () from /cygdrive/c/php/php5ts.dll (gdb) bt #0 0x1000a974 in zend_fetch_debug_backtrace () from /cygdrive/c/php/php5ts.dll #1 0x00a00350 in ??
