after some more testing:
it seems that one can no longer call
"zend_register_internal_class" when the script is already
executing.
my testscript unserializes an object from a class that has
no definition loaded, so we call
php_create_incomplete_class() to setup our "incomplete
class". this used to work just fine...
...
zend_class_entry *php_create_incomplete_class(TSRMLS_D)
{
zend_class_entry incomplete_class;
INIT_OVERLOADED_CLASS_ENTRY(incomplete_class, INCOMPLETE_CLASS, NULL,
incomplete_class_call_func,
incomplete_class_get_property,
incomplete_class_set_property);
BG(incomplete_class) = zend_register_internal_class(&incomplete_class TSRMLS_CC);
return (BG(incomplete_class));
}
...
this together with (atleast) one user-level class will cause
the mentioned crash. i tend to think that something in zend
is causing this. zeev, andi?
BTW: if i call php_create_incomplete_class() from
MINIT(basic_functions) the problem "goes away".
