Hi Derick:
Sorry about leaving php-dev off of the Cc - your reply didn't make it
back to the php-dev list, though you did indeed respond. :)
A couple of followup questions:
1. 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
