This cannot be reproduced with 7.2. So it should be related to PHP 7.3.

/cc @sergeyklay

[jturbide]

Yes I can confirm, 7.3 only

[sergeyklay]

I'll try to sort out ASAP

[dreamsxin]

PHP 7.3.3 will fix the bug.
See https://github.com/php/php-src/commit/03384cae3c46254ccfd5d703b408a0f1d011ee3c#diff-9760ee109b1c5922071fac1e19d117df

if (CE_STATIC_MEMBERS(parent_ce) == NULL) {
    zend_class_init_statics(parent_ce);
}
