sorry I missed " in non-ZTS build " after "affectedï¼since executor_globals
always
available)."
It's: "Only ZTS build affectedï¼since executor_globals/compiler_globals always
available in non-ZTS build"

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 affectedï¼since 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:
----------------
