That's the known issue we have with opcache on 64bit using 64bit binaries. It is due to the memory management. The int64/size_t patch is not causing this bug. > • The 5.5.8 x64 build was even worse.

Again, we have to keep in mind that the x64 is not the int64/size_t. cheers, -- Pierre @pierrejoye | http://www.libgd.org
