## #1762 — l0t3k — 2003-05-20T06:21:43+00:00

im sorry i dont have a diff (my build environment is sensitive at the
moment), but there is a segfault initializing an internal namespace.
simplest reproducing C code is :

<code>
#define MODULE_NAMESPACE "I18N"
zend_namespace *i18n_ns = NULL;

void php_I18N_register_namespace(TSRMLS_DC)
{
 zend_namespace temp_ns;
 temp_ns.name = MODULE_NAMESPACE;
 temp_ns.name_length = strlen(MODULE_NAMESPACE);
 i18n_ns = zend_register_internal_namespace(&temp_ns TSRMLS_CC);
}
</code>

the problem is that the ns->builtin_functions table is not properly
initialized in zend_init_namespace, so a subsequent call to
<code>
 if (ns->builtin_functions) {
  zend_register_functions(ns, ns->builtin_functions, &ns->function_table,
MODULE_PERSISTENT TSRMLS_CC);
 }
</code>

causes the code to crash.
