Does this still happen with any of the actively supported PHP
versions[1]? If so we need a reproduce script and/or a stack
backtrace with debug symbols[2], although on a quick glance this
might be caused by an earlier memory corruption.  Is OPcache
enabled?  Does it also happen with OPcache disabled?
