Package: php5-fpm
Version: 5.6.0~rc2+dfsg-2
Severity: normal
Hello,
Since I switched from 5.5.11 to 5.6.0, php5-fpm crashes immediately while
accessing the home page of the website hosted on this machine.
Each time in syslog records:
Jul 11 01:07:02 mutu kernel: [1258203.337761] php5-fpm[15593]: segfault at
8c ip 00007f22466ebec7 sp 00007fff7a2e3f30 error 4 in opcache.so[7f22466ce000+24000]
Unloading opcache.so (by moving the 05-opcache.ini symlink out of conf.d)
makes PHP usable again.
The output of gdb on the coredump I got generated by php5-fpm is provided
below.
Feel free to ask for any other useful information which may help solving
this !
Thank you
Julien
