Hello peclers again,
here would be a minimal self-contained example of what I had posted
on Wednesday. This crashes (as below) when calling
ZEND_INIT_MODULE_GLOBALS(stack,php_stack_globals_ctor,php_stack_globals_dtor);
in PHP_MINIT_FUNCTION(stack) but runs fine when I would be using
ZEND_INIT_MODULE_GLOBALS(stack,php_stack_globals_ctor,NULL) instead.
#include "php.h"
#include "TSRM.h"
extern zend_module_entry stack_module_entry;
#define stack_module_ptr &stack_module_entry
PHP_MINIT_FUNCTION(stack);
PHP_MSHUTDOWN_FUNCTION(stack);
PHP_MINFO_FUNCTION(stack);
#define phpext_stack_ptr stack_module_ptr
int stack_globals_id;
#define stack_globals(v) TSRMG(stack_globals_id, zend_stack_globals *, v)
ZEND_BEGIN_MODULE_GLOBALS(stack)
ZEND_END_MODULE_GLOBALS(stack)
ZEND_DECLARE_MODULE_GLOBALS(stack);
static function_entry stack_functions[] = {
{NULL,NULL,NULL}
};
zend_module_entry stack_module_entry = {
STANDARD_MODULE_HEADER,
"stack",
stack_functions,
PHP_MINIT(stack), /*module startup*/
NULL, /*module shutdown*/
NULL, /*request startup*/
NULL, /*request shutdown*/
NULL, /*phpinfo*/
NULL /*php version*/
};
ZEND_GET_MODULE(stack)
static void php_stack_globals_ctor (zend_stack_globals *stack_globals TSRMLS_DC) {
}
static void php_stack_globals_dtor (zend_stack_globals *stack_globals TSRMLS_DC) {
}
PHP_MINIT_FUNCTION(stack) {
ZEND_INIT_MODULE_GLOBALS(stack,php_stack_globals_ctor,php_stack_globals_dtor);
}

Sorry for the whining :-) (also will happily accept pointers to RTFM)
