## #103646 — lauri.kentta@gmail.com — 2018-12-28T12:11:59+00:00

I'm investigating the various segfault bugs in PHP 7.3.0.

I was looking at ext/opcache/ZendAccelerator.c:545 and :552, where 
accel_init_interned_string_for_php returns normal strings instead of 
interned strings. As I understand it, there could be (buggy) code which 
frees a string prematurely (possible with normal string but would not 
happen with interned), causing corruption.

Is this a bug or just some Zend quirk?
