I have the same problem. I don't have a test case, cause the bug happens randomly across application. I also get some corrupted variables filled with some random data. Here's the backtrace: #0 0x013795d8 in zval_mark_grey (pz=0x9c5c230) at /root/php-build/php-5.3.4/Zend/zend_gc.c:372 p = 0x1850005 #1 0x01379ebd in gc_mark_roots () at /root/php-build/php-5.3.4/Zend/zend_gc.c:435 No locals. #2 gc_collect_cycles () at /root/php-build/php-5.3.4/Zend/zend_gc.c:664 p = <value optimized out> q = <value optimized out> orig_free_list = <value optimized out> orig_next_to_free = <value optimized out> count = <value optimized out> #3 0x0135c115 in zend_deactivate () at /root/php-build/php-5.3.4/Zend/zend.c:900 No locals. #4 0x01303a8a in php_request_shutdown (dummy=0x0) at /root/php-build/php-5.3.4/main/main.c:1633 report_memleaks = 1 '\001' #5 0x013e7eff in php_apache_request_dtor (r=0x94be720) at /root/php-build/php-5.3.4/sapi/apache2handler/sapi_apache2.c:509 No locals. #6 php_handler (r=0x94be720) at /root/php-build/php-5.3.4/sapi/apache2handler/sapi_apache2.c:681 ctx = 0x94c4168 conf = 0x92b4e18 brigade = 0x94c9968 bucket = <value optimized out> rv = <value optimized out> parent_req = 0x0 ---Type <return> to continue, or q <return> to quit--- #7 0x003d2a4d in ap_run_handler () No symbol table info available. #8 0x003d63f8 in ap_invoke_handler () No symbol table info available. #9 0x003e253e in ap_process_request () No symbol table info available. #10 0x003df2df in ??
