Bug #75357 [NEW]: segfault loading WordPress wp-admin
From: justin at serverpilot dot io
Operating system: Ubuntu 16.04 x64
PHP version: 7.2.0RC3
Package: opcache
Bug Type: Bug
Bug description:segfault loading WordPress wp-admin
Description:
------------
Loading the WordPress admin interface ("/wp-admin") results in a
segfault.
This crash started with RC3 (RC2 worked fine). The problem is still
happening with RC4.
Disabling the opcache fixes the problem.
No non-core extensions are loaded.
Only tested with FPM.
I can provide access to a test server, if desired.
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
