The crashes I'm able to catch with <?php function a(){a();}a(); ?> stop GDB at zend_execute line 1489: zend_ptr_stack_n_push(&EG(arg_types_stack), 2, EX(fbc), EX(object).ptr); However, zend_ptr_stack_n_push seems to handle growth of the stack, and there aren't pointer dereferences anywhere else. Am I looking at the wrong section of code? The wrong stack, maybe? :) 2. Is the PHP stack size configurable, either at run-time or at compile-time? (That is, assuming it's defined by PHP and not a resource limitation/setting in the OS). Thanks in advance, - Dave dave@codewhore.org
