Description:
------------
this test script is reported by ab in his comment to #61133.

and the reason of this crash is different with #61133, so I open this new bug 
entry.



Test script:
---------------
one.php:
<?php

apc_compile_file('two.php');
$data = apc_bin_dump(NULL, NULL);
apc_clear_cache();

apc_bin_load($data, APC_BIN_VERIFY_MD5 | APC_BIN_VERIFY_CRC32);

two.php:
<?php

$a = 'uuu';

Expected result:
----------------
no crash

Actual result:
--------------
php crash with backtrace:
