Bug ID: 220942
Summary: www/mod_php56 opcache makes httpd segfault using
phpPgAdmin 5.1_3
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)

When browsing databases with phpPgAdmin, httpd randomly crashes, with :
[core:notice] [pid 778] AH00052: child pid 803 exit signal Segmentation fault
(11)
Using mpm_prefork or mpm_itk, the result is the same.
It happened on random pages, after clicking around. Mostly coming back to a
page already visited.
After some fiddling, I managed to get a core of httpd and a backtrace :

It pointed to opcache.so, so in php.ini I put opcache.enable=0
Problem disappeared.
I would like to get the opcache back, eventually.
