High volume php.net mirror, opcache reset -> segfaults

Dear PHP webmasters / fellow morror operators / Dmitry :)

I recently upgraded the de2.php.net mirror from 5.4.26 with APC, to 5.5 
with opcache (5.5.16 since yesterday).

While everything works fine, as far as I can see, when I use the ocp.php 
opcache control panel (on a separate, private virtual host of the same 
apache instance) to RESET the opcache (something which would 
happen also when it runs full, I think), I consistently see immediately the 
apache processes dying with segmentation violations, and further 
requests returning "no data", until I restart apache.

Bug report is here: https://bugs.php.net/bug.php?id=67861

I'm writing to you to ask for confirmation, or explanation, or whatever may 
get this resolved.

best regards
  Patrick
