I'm not sure if this was directed at me, but here's my 2 eurocents anyway (using the same script): My GDB output: http://m.bytech.fi/dev/php505gdb.txt And with Valgrind: http://m.bytech.fi/dev/php505valgrind.txt Previous Comments: ------------------------------------------------------------------------ [2005-09-09 09:41:50] [EMAIL PROTECTED] Try to get some more info with valgrind (since the problem is reproducible only by you). ------------------------------------------------------------------------ [2005-09-09 09:39:24] m at aptual dot fi I ran into this problem too, however the segmentation fault only occurs when I use ./configure --with-apxs2=/usr/local/apache/bin/apxs to compile PHP, instead of just ./configure. Yet the segmentation fault is not limited to the apache module, but the sapi/cli/php binary crashes as well. And just as stated by the previous poster, --enable-debug 'fixes' the problem. I'm using Apache 2.0.52, an SMP kernel version 2.6.8 (x86_64) and gcc version 3.3.4. ------------------------------------------------------------------------ [2005-09-08 23:42:49] voxus at mail dot ru Description: ------------ php is crashing when trying to serialize any given object. problem is reproducible on x86_64 arch (known to be ok on x86 with any sane CFLAGS) with php-5.0.5 (5.0.4 is ok), for example - AMD Athlon(tm) 64 Processor 3200+. recompilation with CFLAGS="-O0" or with debug symbols "solves" the problem. Reproduce code: --------------- compile php with CFLAGS="-O2" (yes, nothing more here) execute from cli: class foo { public function bah() { var_dump(serialize($this)); } } $foo = new foo(); $foo->bah(); Expected result: ---------------- var_dump'ed serialized object, i.e. - just string Actual result: -------------- segmentation fault. backtrace from php: (gdb) bt #0 0x00000037ecf6fb9b in memcpy () from /lib/libc.so.6 #1 0x000000000053c8ed in zif_var_export () #2 0x000000000053e419 in php_var_serialize () #3 0x000000000053e4d6 in zif_serialize () #4 0x00000000005c76cb in zend_do_fcall_common_helper () #5 0x00000000005c7941 in zend_do_fcall_handler () #6 0x00000000005bad54 in execute () #7 0x00000000005c721e in zend_do_fcall_common_helper () #8 0x00000000005bad54 in execute () #9 0x0000000000597806 in zend_execute_scripts () #10 0x000000000055e379 in php_execute_script () #11 0x00000000005d1779 in main () ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34435&edit=1
