Description:
------------
5.3.25rc1 and recent snapshots with Opcache-7.01 on Apache-mod_php, these 2 PHPTs fail:
ext/iconv/tests/eucjp2sjis.phpt
ext/iconv/tests/eucjp2utf8.phpt

Both tests return NULL bytes (0x0) about equal to the length of the expected result.

This seems to only happen with Opcache and the tests pass when Opcache is not enabled. These tests PASS on CLI (with or without opcache) using run-tests.php

Test script:
---------------
ext/iconv/tests/eucjp2sjis.phpt
ext/iconv/tests/eucjp2utf8.phpt

You can run these by copying the TEST section from each PHPT into a .php file and running it on Apache by requesting that .php file using a web browser.


Expected result:
----------------
Return strings matching EXPECT sections of PHPTs

Actual result:
--------------
Both tests return NULL bytes (0x0) about equal to the length of the expected result.
