Problem: Return value of zend_get_called_scope() is dereferenced in PhpToken::tokenize() without checking for NULL. Solution: added NULL check for token_class before dereference. Signed-off-by: u.shevchenko@fobos-nt.ru Signed-off-by: crystarm@altlinux.org

Fixes #23700
Adds a NULL check on the return value of zend_get_called_scope() in PhpToken::tokenize() (ext/tokenizer/tokenizer.c), consistent with how this function's return value is checked at other call sites in the codebase. See the linked issue for details — this was flagged by static analysis (statistical NULL-deref checker), not by an observed crash.
