Bug #70985 [NEW]: segfault

From: danjou dot philippe at yahoo dot de Operating system: Debian 8.1 Jessie PHP version: 7.0.0RC8 Package: FPM related Bug Type: Bug Bug description:segfault Description: ------------ Sorry I have only limited information, I saw many segfaults in dmesg. Usually for a short time every minute and then not for hours. I don't know which part of the code causes this (huge drupal site). Here is a gdb backtrace of a coredump. #0 0x00007fb00fca9cc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 #1 0x00007fb00fcad0d8 in __GI_abort () at abort.c:89 #2 0x00007fb00fca2b86 in __assert_fail_base (fmt=0x7fb00fdf3830 "%s%s%s:%u: %s%sAssertion `%s' failed.\n%n", assertion=assertion@entry=0x11cb4e0 "(ref)->gc.u.v.type == 7 || (ref)->gc.u.v.type == 8", file=file@entry=0x11cb4b8 "/opt/php-7.0.0RC8/Zend/zend_gc.c", line=line@entry=226, function=function@entry=0x11cb5f0 <__PRETTY_FUNCTION__.10153> "gc_possible_root") at assert.c:92 #3 0x00007fb00fca2c32 in __GI___assert_fail (assertion=0x11cb4e0 "(ref)->gc.u.v.type == 7 || (ref)->gc.u.v.type == 8", file=0x11cb4b8 "/opt/php-7.0.0RC8/Zend/zend_gc.c", line=226, function=0x11cb5f0 <__PRETTY_FUNCTION__.10153> "gc_possible_root") at assert.c:101 #4 0x0000000000b660f7 in gc_possible_root (ref=0x7fafffae39c0) at /opt/php-7.0.0RC8/Zend/zend_gc.c:226 #5 0x0000000000b42556 in gc_check_possible_root (z=0x7fb004a8f7c0) at /opt/php-7.0.0RC8/Zend/zend_gc.h:136 #6 0x0000000000b425b4 in i_zval_ptr_dtor (zval_ptr=0x7fb004a8f7c0, __zend_filename=0x11c91d0 "/opt/php-7.0.0RC8/Zend/zend_hash.c", __zend_lineno=1305) at /opt/php-7.0.0RC8/Zend/zend_variables.h:60 #7 0x0000000000b468dd in zend_array_destroy (ht=0x7fb004a85480) at /opt/php-7.0.0RC8/Zend/zend_hash.c:1305 #8 0x0000000000b2a7d4 in _zval_dtor_func_for_ptr (p=0x7fb004a85480, __zend_filename=0x11c5f88 "/opt/php-7.0.0RC8/Zend/zend_opcode.c", __zend_lineno=377) at /opt/php-7.0.0RC8/Zend/zend_variables.c:96 #9 0x0000000000b199d3 in _zval_ptr_dtor_nogc (zval_ptr=0x7fb004a70e40, __zend_filename=0x11c5f88 "/opt/php-7.0.0RC8/Zend/zend_opcode.c", __zend_lineno=377) at /opt/php-7.0.0RC8/Zend/zend_variables.h:50 #10 0x0000000000b1abba in destroy_op_array (op_array=0x7fb004a2a448) at /opt/php-7.0.0RC8/Zend/zend_opcode.c:377 #11 0x0000000000b19dc4 in zend_function_dtor (zv=0x7fb004c83a80) at /opt/php-7.0.0RC8/Zend/zend_opcode.c:124 #12 0x0000000000b4660d in zend_hash_destroy (ht=0x7fb004a23350) at /opt/php-7.0.0RC8/Zend/zend_hash.c:1242 #13 0x0000000000b1a80d in destroy_zend_class (zv=0x7fff9d316080) at /opt/php-7.0.0RC8/Zend/zend_opcode.c:289 #14 0x0000000000b45c81 in _zend_hash_del_el_ex (ht=0x1bb8040, idx=348, p=0x1f94a00, prev=0x0) at /opt/php-7.0.0RC8/Zend/zend_hash.c:992 #15 0x0000000000b45d4c in _zend_hash_del_el (ht=0x1bb8040, idx=348, p=0x1f94a00) at /opt/php-7.0.0RC8/Zend/zend_hash.c:1016 #16 0x0000000000b475e8 in zend_hash_reverse_apply (ht=0x1bb8040, apply_func=0xb117ff <clean_non_persistent_class>) at /opt/php-7.0.0RC8/Zend/zend_hash.c:1594 #17 0x0000000000b1340d in shutdown_executor () at /opt/php-7.0.0RC8/Zend/zend_execute_API.c:367 #18 0x0000000000b2e179 in zend_deactivate () at /opt/php-7.0.0RC8/Zend/zend.c:967 #19 0x0000000000a6da21 in php_request_shutdown (dummy=0x0) at /opt/php-7.0.0RC8/main/main.c:1810 #20 0x0000000000c0e991 in main (argc=3, argv=0x7fff9d316908) at /opt/php-7.0.0RC8/sapi/fpm/fpm/fpm_main.c:1972 -- Edit bug report at https://bugs.php.net/bug.php?id=70985&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70985&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70985&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70985&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70985&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70985&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70985&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70985&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70985&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70985&r=support Expected behavior: https://bugs.php.net/fix.php?id=70985&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70985&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70985&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70985&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70985&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70985&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70985&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70985&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70985&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70985&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70985&r=mysqlcfg
