I have got a fix:
$ git diff

to Dmitry: this is because precalculted hash is lost while doing a nop cast...
could you please review it?

Using the right flag to enable opcache with php-cli, the output is also
incorrect. I tried with php 5.5.3, 5.5.4 and the latest snapshot.
thank you for your help Cedric

@laruence
what makes sense is to use the right flag for cli runtime : opcache.enable is
for non-cli PHP whereas opcache.enable_cli is for cli version.
Just try with the good option in order to see the bug :
$ php55 -d opcache.enable_cli=1 -d opcache.optimization_level=0xffffffff
/tmp/1.php
