Sorry. It's the first field in the longjmp record.

(gdb) p $rax
$1 = 17185954536
(gdb) up
#1  0x00007ffaa1ad8f27 in ntdll!RtlUnwindEx ()
   from C:\WINDOWS\SYSTEM32\ntdll.dll
(gdb) up
#2  0x00007ffaa0671f4a in msvcrt!_setjmpex ()

$2 = (sys_jmp_buf *) 0x4005cdae8 <main_thread+224>


(rax is 17185954536 = 4005CDAE8h).
