Description:
------------
Even though it does not make sense to call opcache_compile_file() (i.e. attempting to run a preload script) on the CLI, it would make sense to add a specific error message.

Currently I get a segfault:



Test script:
---------------
php -r "opcache_compile_file('test.php');"

Expected result:
----------------
An error message

Actual result:
--------------
Segmentation fault (core dumped)

Given that the built-in web server runs under the CLI SAPI, it may
well make sense to call opcache_compile_file().

Anyhow, I can't reproduce the segfault.  Please provide a
backtrace[1].

I believe this is the same issue as bug #78429, which has been fixed in the meantime. (The relevant detail absent from this report is that it requires opcache.enable_cli=0.)
