Anyone who’s looking to upgrade, or install a new server and require Zend Optimizer to run Zend Encoder / Zend Guard encoded programs -
Zend Optimizer 3.3.0a is broken. It has some broken SHM setup calls in it, which cause it to execute sometimes, but abort early. This breaks ‘interactive’ mode, as well as pipes.
I have confirmed this behavior on Linux (32 bit) and Linux x86_64 bit platforms.
Below are snippits from an strace (for clarity) of ‘strace php -a’; this problem is not exhibited in 3.2.8 or earlier versions.
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b5dfbf94000
lseek(0, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek)
close(0) = 0
munmap(0x2b5dfbf94000, 4096) = 0
ioctl(-1, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fffaeb6b7a0) = -1 EBADF (Bad file descriptor)
mmap(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b5e0189c000
mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b5e0199d000
read(4294967295, 0xd75cb0, 8192) = -1 EBADF (Bad file descriptor)
I suggest everyone stick to Zend Encoder 3.2.8 until this is resolved.
