sorry I missed " in non-ZTS build " after "affected，since executor_globals 
always 
available)."

It's: "Only ZTS build affected，since executor_globals/compiler_globals always 
available in non-ZTS build"

Description:
------------
when debug using GDB, sometime ____executor_globals failed to execute 
because in some module eg:zend_gc.c did have zend_executor_global exposed(Only 
ZTS 
model affected，since executor_globals always available).

Test script:
---------------
(gdb) b gc_zval_possible_root
Breakpoint 1 at 0x1005aa7d0: file zend_gc.c, line 132.
(gdb) r circle.php 
Starting program: /Users/reeze/Opensource/php-src/sapi/cli/php circle.php
Reading symbols for shared libraries ++++++.......................... done

Breakpoint 1, gc_zval_possible_root (zv=0x100dcbb58, tsrm_ls=0x100e009b0) at 
zend_gc.c:132
warning: Source file is more recent than executable.
132             if (UNEXPECTED(GC_G(free_list) != NULL &&
(gdb) printzv zv
No symbol "zend_executor_globals" in current context.

Expected result:
----------------
print zval correctly

Actual result:
--------------
No symbol "zend_executor_globals" in current context.
