Description:
------------
Hi,

In PHP 5.5+ internal changes lists:-

"""
Removed the execute_data->CVs field. The VM compiled variables are always allocated immediately after the execute_data structure, and are now accessed by the offset from the execute_data base pointer instead of via execute_data->CVs. You can use the EX_CV_NUM() macro to access compiled variables by number.
"""

But the .gdbinit file has not been updated and is still trying to use the CVs member in print_cvs

Test script:
---------------
$ gdb -p <php pid>
(gdb) source .gdbinit
(gdb) print_cvs

Expected result:
----------------
The compiled variables are displayed.

Actual result:
--------------
(gdb) print_cvs
There is no member named CVs.
