The test case  ext/sockets/tests/socket=5Frecvmsg.php  has following output
on x86=5F64:

=3D=3D=3D=3D=3D=3D=3D
...
1 Array
2 (
3    [name] =3D> Array
4        (
5            [family] =3D> 10
6            [addr] =3D> ::1
7            [port] =3D> 7001
8            [flowinfo] =3D> 0
9            [scope=5Fid] =3D> 0
10        )
11
12    [control] =3D> Array
13       (
14            [0] =3D> Array

16                    [level] =3D> 41
17                    [type] =3D> 50
18                    [data] =3D> Array
19                       (
20                            [addr] =3D> ::1
21                            [ifindex] =3D> 1
22                        )
23                )
24        )
...
=3D=3D=3D=3D=3D=3D=3D
This is output  by c
function:"socket=5Frecvmsg"(/home/work/php/php/ext/sockets/sendrecvmsg.c:21=
4),
 which returns a struct "executor=5Fglobals.current=5Fexecute=5Fdata".

The struct  is defined as :

(gdb)  ptype executor=5Fglobals.current=5Fexecute=5Fdata
type =3D struct =5Fzend=5Fexecute=5Fdata {
    const zend=5Fop *opline;
    zend=5Fexecute=5Fdata *call;
    zval *return=5Fvalue;
    zend=5Ffunction *func;
    zval This;
    zend=5Fexecute=5Fdata *prev=5Fexecute=5Fdata;
    zend=5Farray *symbol=5Ftable;
    void **run=5Ftime=5Fcache;
    zval *literals;
} *

Where do  the above output values  (line 18-21) store in the struct
=5Fzend=5Fexecute=5Fdata ?


Thanks,

Sam
