Arginfo Mismatch For Optional Parameters View as Markdown

Hello,

I am a little confused about this while working on my extension. I've
compiled PHP with --enable-debug and this only produces a fatal error
when used with that flag, without debug it runs fine.

"Fatal error: Arginfo / zpp mismatch during call of
raylib\Vector3::__construct()"

Here is the c code snippet of my code that produces the error:

ZEND_BEGIN_ARG_INFO_EX(arginfo_vector3__construct, 0, 0, 0)
ZEND_ARG_TYPE_MASK(0, x, IS_DOUBLE, "0")
ZEND_ARG_TYPE_MASK(0, y, IS_DOUBLE, "0")
ZEND_ARG_TYPE_MASK(0, z, IS_DOUBLE, "0")
ZEND_END_ARG_INFO()
PHP_METHOD(Vector3, __construct)
{
double x;
bool x_is_null = 1;

double y;
bool y_is_null = 1;

double z;
bool z_is_null = 1;

ZEND_PARSE_PARAMETERS_START(0, 3)
    Z_PARAM_OPTIONAL
    Z_PARAM_DOUBLE_OR_NULL(x, x_is_null)
    Z_PARAM_DOUBLE_OR_NULL(y, y_is_null)
    Z_PARAM_DOUBLE_OR_NULL(z, z_is_null)
ZEND_PARSE_PARAMETERS_END();

php_raylib_vector3_object *intern = Z_VECTOR3_OBJ_P(ZEND_THIS);

if (x_is_null) {
    x = 0.0f;
}

if (y_is_null) {
    y = 0.0f;
}

if (z_is_null) {
    z = 0.0f;
}

intern->vector3->data = (Vector3) {
    .x = (float) x,
    .y = (float) y,
    .z = (float) z
};

}

Then the line of PHP code:
$position = new Vector3(4.0, 2.0, 4.0);

I am confused because these are all optional parameters, and it should
work? If I exclude the parameters in my PHP code it works fine.

If I swap the following:

ZEND_BEGIN_ARG_INFO_EX(arginfo_vector3__construct, 0, 0, 0)
ZEND_ARG_TYPE_MASK(0, x, IS_DOUBLE, "0")
ZEND_ARG_TYPE_MASK(0, y, IS_DOUBLE, "0")
ZEND_ARG_TYPE_MASK(0, z, IS_DOUBLE, "0")
ZEND_END_ARG_INFO()

For the following:

ZEND_BEGIN_ARG_INFO_EX(arginfo_vector3__construct, 0, 0, 0)
ZEND_ARG_INFO(0, x)
ZEND_ARG_INFO(0, y)
ZEND_ARG_INFO(0, z)
ZEND_END_ARG_INFO()

Then it works fine. Can I not use ZEND_ARG_TYPE_MASK in this context?
I only put the type mask with the default value so it works better
with PHP's built-in reflection, so is this not possible? I've seen
similar uses with Tidy and Soap extensions so I'm a little baffled on
why it's an issue here. I think the only difference is that where the
ARG_INFO is, is in the header files versus the C files of those
extensions.

Thanks,
