Edit report at http://bugs.php.net/bug.php?id=54491&edit=1 ID: 54491 User updated by: msamson at chowly dot com Reported by: msamson at chowly dot com Summary: Crash when using mongodb or couchdb database adapters Status: Open Type: Bug Package: Reproducible crash Operating System: Fedora 14 x64 PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Finally got a backtrace: /Zend/Zend_execute_API.c:437 437 Z_DELREF_PP(zval_ptr); There is a mention in another frame about requesting php shutdown. Then higher, it says it will cleanup a closure. Sadly, no execute and zbacktrace output was empty.

Please see https://bugzilla.redhat.com/show_bug.cgi?id=694630 This was initially thought as a fedora packaging bug, but even a compiled from source php is producing the same error. Test script: --------------- Please see https://bugzilla.redhat.com/show_bug.cgi?id=694630 for a simple script. Actual result: -------------- Tested is using a 2 different virtual machines both running Fedora 14 x64. One with php from yum, the other compiled. gdb reports no backtrace and says there is no stack. Apache 2.2 crashes, running php-cli too. relevant strace output: array(0) { } } </div> </div> </body> </html>) = 1681 write(2, "zend_mm_heap corrupted\n", 23zend_mm_heap corrupted ) = 23 exit_group(1) = ? Another one with sessions: pwrite(3, "cart|a:1:{s:2:\"id\";C:7:\"MongoId\""..., 63, 0) = 63 close(3) = 0 close(4) = 0 write(2, "zend_mm_heap corrupted\n", 23zend_mm_heap corrupted ) = 23 exit_group(1) It appears php is crashing at the end of the request just before delivering the content, when a database of some sort is used. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54491&edit=1
